1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8) 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, 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. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust.

Solvothermal Synthesis of CuFe2O4@rGO: Efficient Catalyst for C-O Cross Coupling and N-arylation Reaction under Ligand-Free Condition was written by Nakhate, Akhil V.;Yadav, Ganapati D.. And the article was included in ChemistrySelect in 2017.Category: ethers-buliding-blocks This article mentions the following:

The copper ferrite supported reduced graphene oxide (CuFe2O4@rGO) synthesis by solvothermal process has been reported. The prepared CuFe2O4@rGO catalyst was used for C-O and C-N cross coupling reactions. The activity of the catalyst was compared with com. Cu2O, CuO and CuFe2O4 for C-O cross coupling of iodobenzene with phenol. The CuFe2O4@rGO was the best catalyst with 97% conversion towards iodobenzene at 100 °C under ligand free condition which is otherwise normally used. The virgin and five times reused CuFe2O4@rGO catalyst was characterized by XRD, SEM, FTIR, TEM, N2-adsorption desorption isotherm, XPS and TGA anal. The effect of solvent, nature of base, speed of agitation, mole ratio, catalyst loading and temperature were studied for phenol and iodobenzene reaction and its activity was further explored in N-arylation of indole with iodobenzene. The best conversion and yield were achieved at 100 °C at 1×10-3 g/cm3 catalyst loading. Notably, CuFe2O4@rGO was reusable without any loss of catalytic activity for five recycles. Reaction mechanism and kinetics are also presented. The overall process is novel and green. In the experiment, the researchers used many compounds, for example, 1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8Category: ethers-buliding-blocks).

They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons.

Selective, Electrophilic Fluorinations Using N-Fluoro-o-benzenedisulfonimide was written by Davis, Franklin A.;Han, Wei;Murphy, Christopher K.. And the article was included in Journal of Organic Chemistry in 1995.Reference of 56619-93-3 This article mentions the following:

The synthesis of N-fluoro-o-benzenedisulfonimide (NFOBS) and its use as an electrophilic fluorinating reagent with nucleophilic substrates is described and compared with that of N-fluorobenzenesulfonimide (NFSi). NFOBS is prepared in three steps in 81% overall yield from com. available o-benzenedisulfonic acid and involves treatment of o-benzenedisulfonimide with dilute fluorine (10% F2/N2). Reaction of NFOBS with metal enolates, silyl enol ethers, and 1,3-dicarbonyl compounds affords the corresponding α-fluoro compounds in yields up to 95%, with good control of mono- and difluorination. Fluorination of ortho-metalated aromatic compounds was achieved in modest to good yields (10-80%). While the reactivities of NFOBS and NFSi are similar, better yields were observed with the former reagent in the fluorination of metal enolates, Grignard and lithium reagents, while NFSi gave better results with the ortho-lithiated aromatic substrates. The available evidence suggests an SN2-type mechanism for the fluorination of nucleophilic substrates by these reagents. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3Reference of 56619-93-3).

Internalization of a peptide into multilamellar vesicles assisted by the formation of an α-oxo oxime bond was written by Richard, Antoine;Bourel-Bonnet, Line. And the article was included in Chemistry – A European Journal in 2005.Safety of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol This article mentions the following:

As part of a drug-delivery project, we designed and synthesized a novel hydroxylamine cholesterol-based anchor to ensure the chemoselective ligation of recognition patterns onto multilamellar vesicles by oxime ligation. The entry of a glyoxylyl peptide into the vesicles was unexpectedly assisted by the formation of the α-oxo oxime bond. We studied extensively the kinetic and thermodn. aspects of this phenomenon. Briefly, for a glyoxylyl peptide, the speed and ability to enter the vesicle were dependent upon (1) the presence of a hydroxyl-amine anchor of the type Chol-E3ONH2, (2) the amount of peptide engaged in the ligation and (3) the flip-flop motion permitted by the different formulations, in which the presence of cholesterol seems to play an important role. In the experiment, the researchers used many compounds, for example, 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol (cas: 60221-37-6Safety of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol).

Ignition-delay measurement for drop test with hypergolic propellants: Reactive fuels and hydrogen peroxide was written by Kang, Hongjae;Park, Seonghyeon;Park, Youngchul;Lee, Jongkwang. And the article was included in Combustion and Flame in 2020.Recommanded Product: 112-49-2 This article mentions the following:

Green hypergolic propellants have been extensively studied. In the present study, we attempted to improve the measurement technique for the ignition delay in hypergolic reactions by using a drop-test apparatus The evaluation method for the hypergolicity is important because an increase in the diversification of green hypergolic combinations is inevitable. Hydrogen peroxide (90 wt%) was used as an oxidizer, and six different reactive fuels were prepared Sodium borohydride was utilized as an ignition source for the fuels. Optical and acoustic sensors were employed to reliably measure the ignition delay. The proposed measurement technique used in this study accurately reflected the phys. phenomena of the hypergolic interactions. The tech. limitations in the conventional measurement technique using a high-speed camera were exptl. investigated. Liquid-phase reactions were dominant in the hypergolic reactions of the glyme-based reactive fuels. Gas-phase reactions significantly influenced the hypergolic reactions of most of the amine-based reactive fuels. The pyridine-based reactive fuel had a longer delay time for the gas-phase reaction process than the liquid-phase reaction process. Recognizing the rate-determining step of the hypergolic ignition is necessary for not only designing a rocket injector but also reducing combustion instability, e.g., reactive stream separation In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Recommanded Product: 112-49-2).

Tree peony essential oil (EO) is a critical material for flavor and function in the industrial fields of perfume, medicine and food. To conduct an overall anal. of different varieties of tree peony EOs, the composition, aroma characteristics and antioxidant activity of ZiBan and FengDan EOs were analyzed by two-dimensional gas chromatog. and time-of-flight mass spectrometry (GC × GC-TOF/MS) and the odor activity value (OAV). A total of 151 and 123 compounds were identified in ZiBan and FengDan EOs, resp., in which ZiBan EO was characterized by alc., alkane and acid, and FengDan EO was represented by aldehyde, alc. and terpene. Nevertheless, there were great differences in the content of coexisting substances in the two kinds of EOs. The aroma result indicated that the characteristic aroma and intensity of the two kinds of tree peony EOs were completely different; the aroma of ZiBan EO was mainly composed of fruity and floral aromas, whereas that of FengDan EO primarily consisted of fruity, fatty, grass and floral odors. The antioxidant activities of ZiBan EO was better than that of FengDan EO. The total antioxidant activities of ZiBan and FengDan EOs were found to be 0.020 mg Vc/mL EO and 0.003 mg Vc/mL EO, while the DPPH radical scavenging abilities of ZiBan and FengDan EOs were 24.77% and 21.60%, resp.
