The present paper describes the 1, 1-dichlorocyclopropane formation from highly electron-deficient carbon-carbon double bonds conjugated, in the main, with two cyano groups by allowing to react with trichloroacetic acid. β-Trichloromethylation was indicated in some cases. Path of the 1, 1-dichlorocyclopropane formation is presumed not to involve dichlorocarbene, but β-trichloromethylated intermediate.
本文描述了通过与三氯乙酸反应,从主要与两个氰基连接的高电子缺乏的碳碳双键形成1, 1-二氯环丙烷。在某些情况下,表明存在β-三氯甲基化。推测1, 1-二氯环丙烷的形成路径并不涉及二氯碳烯,而是β-三氯甲基化的中间体。
