conversion of methylene chloride in solutions of several allyl and diallyl episulphides 1–6 into the corresponding unsaturated derivatives 7–12. The desulphurization process, which occurs through a plausible chain electron-transfer mechanism, rapid and may proceed in a fashion that preserves the stereochemistry of the starting episulphide.
催化量的铵盐AB会诱导二氯甲烷在几种烯丙基和二烯丙基环氧乙烷1–6的溶液中转化为相应的不饱和衍生物7–12。脱硫过程是通过合理的链电子转移机制而迅速进行的,并且可能以保留起始硫化物的立体化学的方式进行。
