Microemulsion polymerization of styrene stabilized by sodium dodecyl sulfate and diethylene glycol monoalkyl ether was written by Chern, C. S.;Liu, C. W.. And the article was included in Colloid and Polymer Science in 2000.Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

The effects of diethylene glycol monoalkyl ether cosurfactants on the formation of an oil-in-water styrene (ST) microemulsion and the subsequent free radical polymerization were studied. Na dodecyl sulfate was used as the surfactant. The pseudo three-component phase diagram (macroemulsion, microemulsion and lamellar gel phases) was constructed for each cosurfactant. The primary parameters selected for the polymerization study are the concentrations of cosurfactant and styrene. The number of latex particles nucleated is much smaller than that of the microemulsion droplets initially present in the reaction system. Limited flocculation of the latex particles occurs to some extent during polymerization The diethylene glycol monoalkyl ether group tends to enhance the latex stability. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol

Sym. and unsym. N,N’-disubstituted as well as trisubstituted ureas/thioureas R¹NHC(X)N(R²)R³ (R¹ = Ph, t-Bu, cyclohexyl, etc.; R² = Ph, t-Bu, furan-2-ylmethyl, etc.; R³ = H, Me; R²R³ = morpholin-4-yl, piperidin-1-yl; X = O, S) by the hydroamination of isocyanates/isothiocyanates R¹N=C=X, and various phosphathioureas R¹NHC(S)PPh₂ by the hydrophosphination of isothiocyanates R¹N=C=S have been synthesized in good to excellent yields under catalyst-free and mild conditions. This protocol is also applicable for the efficient synthesis of chiral ureas/thioureas e.g., (S)-1-(1-phenylethyl)-3-(p-tolyl)urea and common herbicides, such as fenuron and monuron. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Application In Synthesis of 2-Methoxyethylamine).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

A Boron-Boron Double Transborylation Strategy for the Synthesis of gem-Diborylalkanes was written by Docherty, Jamie H.;Nicholson, Kieran;Dominey, Andrew P.;Thomas, Stephen P.. And the article was included in ACS Catalysis in 2020.Name: 4-Benzyloxyphenol The following contents are mentioned in the article:

1,1-Diborylalkanes RCH₂CH(Bpin)₂ were prepared by double borylation of α-alkynes catalyzed by 9-borabicyclononane via transborylation pathway. Olefin hydroboration reactions provide efficient access to synthetically versatile and easily handled organoboronic esters. In this study, we demonstrate that the com. available organoborane reagent 9-borabicyclo[3.3.1]nonane (H-B-9-BBN) can serve as a catalyst for the sequential double hydroboration of alkynes using pinacolborane (HBpin). This strategy, which is effective for a wide range of terminal alkynes, is predicated upon a key C(sp³)-B/B-H transborylation reaction. Transition-state thermodn. parameters and 10-boron-isotopic labeling experiments are indicative of a σ-bond metathesis exchange pathway.

Evaluation of potential organic frothers for copper-molybdenum sulfide mineral flotation was systematically studied. A frother characterization methodol. including parameters of the frothing system, namely, initial dynamic frothing index and initial dynamic froth collapse rate are used in the anal. of dynamic frothing of the reagent and in selection of potential frothers. Flotation tests using organic reagents as frothers for the ore are conducted to determine the metallurgical performance of the potential frothers.

Passerini-Smiles Reaction of α-Ketophosphonates: Platform for Phospha-Brook/Smiles Embedded Cascades was written by Cheibas, Cristina;Fincias, Nicolas;Casaretto, Nicolas;Garrec, Julian;El Kaim, Laurent. And the article was included in Angewandte Chemie, International Edition in 2022.Category: ethers-buliding-blocks The following contents are mentioned in the article:

The Passerini-Smiles reactions of α-ketophosphonates with nitrophenols has been used as a platform to observe complex cascades involving multiple Smiles transfers coupled with phospha-Brook rearrangement. When using 4-nitrophenols a rare 1,3-Truce-Smiles rearrangement is observed leading to diarylacetamide derivatives 2-Nitro-derivatives lead to a completely different reactivity pattern that may be explained by a nitro to nitroso conversion followed by a σ-π metathesis. All mechanistic assumptions are confirmed by DFT calculations performed on both families of adducts. The potential of this work has been further demonstrated by the use of N-aryl α-ketoamides as alternative starting materials for these cascades as well as the disclosure of new aza-Nazarov access to hydroxy-indolones.

A Tandem Dehydrogenation-Driven Cross-Coupling between Cyclohexanones and Primary Amines for Construction of Benzoxazoles was written by Xu, Biping;Su, Weiping. And the article was included in Angewandte Chemie, International Edition in 2022.Recommanded Product: 109-85-3 The following contents are mentioned in the article:

Herein, authors report a transition metal-free, operationally simple, general method for straightforward syntheses of 2-substituted benzoxazoles from readily available cyclohexanones and aliphatic primary amines by an imine α-oxygenation-initiated cascade reaction sequence. The key to achieving high selectivity and excellent functional-group tolerance is the use of TEMPO as a mild oxidant that selectively oxidizes the reaction intermediates through its multiple reactivity modes, thus facilitating the individual steps to proceed in succession. More than 70 substrate combinations are disclosed, demonstrating the reliability of this protocol to synthesize structurally diverse products, including marketed drugs, drug candidate, and natural products that are unattainable by the existing methods.
