Abstract

The attack of the thiol sulfur atom (P–SMe) on the methine carbon as the main route of the new reaction of dichloromethylarenes with S-methyl diethylthiophosphinate has been predicted and experimentally confirmed on the basis of the electronic structure of the S-alkyl esters of P(IV) acids. The processes of the mono- and di(dechloromethylthioylation) of dichloromethyl group have been realized. A new approach to the synthesis of the arenecarbaldehyde dimethyl dithioacetals has been developed avoiding the use of gaseous highly toxic methyl mercaptan.

S-甲基二乙基硫代次膦酸酯与二氯甲基芳烃的单和二（脱氯甲基硫基化）

摘要

基于S-烷基酯的电子结构，已预测并实验证实了硫醇硫原子（P-SMe）对次甲基碳的攻击，这是二氯甲基芳烃与S-甲基二乙基硫代次膦酸酯新反应的主要途径。P（IV）酸。已经实现了二氯甲基基团的单和二（脱氯甲基硫基化）过程。已经开发了一种新的合成芳烃甲醛二甲基二硫缩醛的方法，避免了使用气态高毒性甲基硫醇。
