(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Formula: C8H10O2

Efficient visible light initiated one-pot syntheses of secondary amines from nitro aromatics and benzyl alcohols over Pd@NH2-UiO-66(Zr) was written by Hao, Mingming;Li, Zhaohui. And the article was included in Applied Catalysis, B: Environmental in 2022.Formula: C8H10O2 This article mentions the following:

Pd@NH2-UiO-66(Zr), with small-sized Pd nanoparticles encapsulated inside the cavities of NH2-UiO-66(Zr), was obtained via a double-solvent impregnation followed by a photoreduction process, which shows superior activity for the visible light initiated syntheses of secondary amines from nitro compounds and alcs., via a sequential photocatalytic hydrogenation of nitro compounds/dehydrogenation of alcs., condensation of amines and aldehydes to imines, and the hydrogenation of imines. Simultaneous consumption of photogenerated electrons/holes in the photocatalytic hydrogenation of nitro compounds to amines and dehydrogenation of alcs. to aldehydes promotes the whole reaction. Due to the confinement effect of the cavity and the small-sized Pd nanoparticles, Pd@NH2-UiO-66(Zr) shows significantly superior performance as compared with Pd/NH2-UiO-66(Zr), in which larger Pd nanoparticles are deposited on the surface. This study provides an efficient and green strategy for the production of secondary amines and highlights the great potential of using M/MOFs nanocomposites as multifunctional catalysts for light induced one-pot tandem reactions. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Formula: C8H10O2).

3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Reference of 57179-35-8

Design, synthesis, and evaluation of dihydropyranopyrazole derivatives as novel PDE2 inhibitors for the treatment of Alzheimer’s disease was written by Zhou, Yan;Li, Jinjian;Yuan, Han;Su, Rui;Huang, Yue;Huang, Yiyou;Li, Zhe;Wu, Yinuo;Luo, Haibin;Zhang, Chen;Huang, Ling. And the article was included in Molecules in 2021.Reference of 57179-35-8 This article mentions the following:

In this study, (R)-LZ77 was obtained as a hit compound with moderate PDE2 inhibitory activity (IC50 = 261.3 nM) using a high-throughput virtual screening method based on mol. dynamics. Then, 28 dihydropyranopyrazole derivatives I [R1 = H, CH3O, Cl; R2 = H, CH3, CH3O, etc.; R3 = H, CH3, C6H5; R4 = H, CH3O, Cl, etc; R5 = NH2, (CH3)2N; n = 1, 2, 3] and II [R6 = Cl, CF3; n = 0, 2, 3] were designed and synthesized as PDE2 inhibitors. Among them, compound (+)-I [R1 = H; R2 = CH3O; R3 = CH3; R4 = CF3; R5 = NH2; n = 1] was the most potent PDE2 inhibitor, with an IC50 value of 41.5 nM. The mol. docking of PDE2-(+)-I [R1 = H; R2 = CH3O; R3 = CH3; R4 = CF3; R5 = NH2; n = 1] revealed that the 4-(trifluoromethyl)benzyloxyl side chain of the compound enters the H-pocket and forms strong hydrophobic interactions with L770/L809/F862, which improves inhibitory activity. The above results may provide insight for further structural optimization of highly potent PDE2 inhibitors and may lay the foundation for their use in the treatment of AD.

Poly(ionic liquid)s with branched side chains: polymer design for breaking the conventional record of ionic conductivity was written by Ikeda, Taichi. And the article was included in Polymer Chemistry in 2021.Application In Synthesis of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol This article mentions the following:

Poly(ionic liquid)s with non-branched, di-branched, and tri-branched side chains were synthesized using cationic glycidyl triazolyl polymers (GTPs). Based on the analyses of these cationic GTPs, the effects of side-chain branching on phys. properties, such as glass transition temperature and ionic conductivity, were discussed. It was confirmed that the ionic conductivity increased with the degree of side-chain branching. Despite being a high-mol.-weight polymer (1.9 x 106 Da), GTP with tri-branched side chains exhibited a high ionic conductivity of 3.6 x 10-5 M at 25°C under dry conditions, which is higher than the benchmark value of the conventional poly(ionic liquid)s proposed by Shaplov, Marcilla, and Mecerreyes (3.0 x 10-5 M at 25°C, dry conditions, mol. weight >105 Da). From the anal. based on the electrode polarization model, the higher ionic conductivity of cationic GTPs with branched side chains can be attributed to their higher conducting ion mobility in the polymer matrix. These results indicate that side-chain branching is effective in breaking the conventional limit of ionic conductivity of poly(ionic liquid)s.

And the article was included in Molecules in 2021.Reference of 3929-47-3 This article mentions the following:

We present the intra- and inter-mol. organocatalysis of SN2 fluorination using CsF by crown ether to estimate the efficacy of the promoter and to elucidate the reaction mechanism. The yields of intramol. SN2 fluorination of the veratrole substrates are measured to be very small (<1% in 12 h) in the absence of crown ether promoters, whereas the SN2 fluorination of the substrate possessing a crown ether unit proceeds to near completion (~99%) in 12 h. We also studied the efficacy of intermol. rate acceleration by an independent promoter 18-crown-6 for comparison. We find that the fluorinating yield of a veratrole substrate (leaving group = -OMs) in the presence of 18-crown-6 follows the almost identical kinetic course as that of intramol. SN2 fluorination, indicating the mechanistic similarity of intra- and inter-mol. organocatalysis of the crown ether for SN2 fluorination. The calculated relative Gibbs free energies of activation for these reactions, in which the crown ether units act as Lewis base promoters for SN2 fluorination, are in excellent agreement with the exptl. measured yields of fluorination. The role of the metal salt CsF is briefly discussed in terms of whether it reacts as a contact ion pair or as a “free” nucleophile F–.

A simple protocol to overcome the explosive pentafluoroethylation of carbonyl compounds by HFC-125 is described. The use of potassium (K) bases with triglyme or tetraglyme as a solvent safely yields the pentafluoroethylation products in good to high yields. The exptl. results suggest that an encapsulation of the K cation by glymes as K(glyme)2 inhibits the contact between the K cation and the reactive anionic pentafluoroethyl counterion, preventing their transformation into KF and explosive tetrafluoroethylene (TFE). The generation of sterically demanding [K(G3)2]+ and [K(G4)2]+ is an effective way as an unstable pentafluoroethyl anion reservoir.

Phosphatidylinositol 3-kinase α (PI3Kα) is the most frequently mutated kinase in human cancers, making it an attractive therapeutic target for cancer treatment. The authors identified a structurally novel PI3Kα H1047R mutant inhibitor Hit-01 (5,7-dichloro-2,3-di(furan-2-yl)quinoxaline) (EC50 = 76.0 μM) through a high-throughput screening campaign. Chem. optimizations enabled the authors to discover compound 7b (6-bromo-7-(2-fluorophenyl)-2,3-di(furan-2-yl)quinoxaline), which strongly inhibited PI3Kα H1047R mutant with an EC50 value of 0.137 μM, over 500-fold more potent than Hit-01. Western blotting anal. suggested that 7b could decrease the phosphorylation level of p-AKT, another proof that 7b inhibited PI3Kα H1047R function. Cell viability assay revealed that 7b inhibited HCT116 cancer cell growth with an IC50 value of 11.23 μM. In addition, 7b was found to arrest cell cycle at G1 phase and induce cell apoptosis via up-regulation of caspase-3, caspase-8 and caspase-9 protein expressions.

Structural complexity through multicomponent cycloaddition cascades enabled by dual-purpose, reactivity regenerating 1,2,3-triene equivalents was written by Wender, Paul A.;Fournogerakis, Dennis N.;Jeffreys, Matthew S.;Quiroz, Ryan V.;Inagaki, Fuyuhiko;Pfaffenbach, Magnus. And the article was included in Nature Chemistry in 2014.Safety of 1,4-Dimethoxy-2-butyne This article mentions the following:

Multicomponent reactions allow for more bond-forming events per synthetic operation, enabling more step- and time-economical conversion of simple starting materials to complex and thus value-added targets. These processes invariably require that reactivity be relayed from intermediate to intermediate over several mechanistic steps until a termination event produces the final product. Here, the authors report a multicomponent process in which a novel 1,2,3-butatriene equivalent (TMSBO: TMSCH2C CCH2OH) engages chemospecifically as a two-carbon alkyne component in a metal-catalyzed [5 + 2] cycloaddition with a vinylcyclopropane to produce an intermediate cycloadduct. Under the reaction conditions, this intermediate undergoes a remarkably rapid 1,4-Peterson elimination, producing a reactive four-carbon diene intermediate that is readily intercepted in either a metal-catalyzed or thermal [4 + 2] cycloaddition TMSBO thus serves as an yne-to-diene transmissive reagent coupling two powerful and convergent cycloadditions-the homologous Diels-Alder and Diels-Alder cycloadditions-through a vinylogous Peterson elimination, and enabling flexible access to diverse polycycles.

The working pairs of HFCs + organic absorption solvents are commonly used in absorption systems. In this work, the vapor-liquid equilibrium (VLE) data of HFC-32 + DMETrEG at (293.15-343.15) K and HFC-32 + NMP at (323.15-343.15) K were measured in a dual cycle apparatus The VLE data were correlated by Antione-type equation, NRTL, and PR + MHV1 + NRTL model, resp. The predicted VLE data showed a good agreement with the exptl. VLE data. NRTL model was recommended to predict the VLE data and characteristic of solution for HFC-32 + DMETrEG and HFC-32 + NMP, compared to PR + MHV1 + NRTL model. The comparison of VLE characteristics for five binary mixtures (HFC-32 + DMETrEG, HFC-32 + NMP, HFC-32 + DMF, HFC-32 + DMAC, and HFC-32 + DMEDEG) was carried out. The system pressures of HFC-32 + DMETrEG and HFC-32 + NMP were lower than other three mixtures, and the neg. deviations from Raoult’s law of HFC-32 + DMETrEG and HFC-32 + NMP were larger than the others, which indicated that the two mixtures were more suitable as the working fluids for absorption system. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Application In Synthesis of 2,5,8,11-Tetraoxadodecane).

2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Application In Synthesis of 2,5,8,11-Tetraoxadodecane
