Self-assembly of reverse micelle nanoreactors by zwitterionic polyoxometalate-based surfactants for high selective production of β-hydroxyl peroxides was written by Hu, Guicong;Chang, Wen;An, Sai;Qi, Bo;Song, Yu-Fei. And the article was included in Chinese Chemical Letters in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:
A zwitterionic polyoxymetalate (POM) based surfactant was synthesized by covalently grafting two cationic long alkyl tails onto the lacunary site of [PW11O39]7-. With decreased electrostatic repulsions and increased hydrophobic effect, the POM-based reverse micelles with an average diameter of 5 nm were obtained. Interestingly, when these reverse micelles were applied for catalyzing the oxidation of styrene, an unprecedented β-hydroxyl peroxide compound, 2-hydroxyl-2-phenylethan-1-tert-butylperoxide, was produced with high selectivity of 95.2%. In comparison, the cetyltrimethylammonium electrostatically encapsulated POMs mainly generated the epoxides or 1,2-diols. A free radical mechanism were proposed for the oxidation reaction catalyzed by the zwitterionic POM surfactants. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Category: chlorides-buliding-blocks).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Category: chlorides-buliding-blocks
