elimination of arene- and alkanethiol from diaryl and dialkyl dithioacetals, in the presence of copper(I) or copper(II) salt plus tertiary amine, to produce the corresponding aryl and alkyl vinyl sulfides, respectively, has been studied. The employment of a combination of 2 mol equiv. of CuCl2 and 2 mol equiv. of N,N-diisopropylethylamine is most favorable.
已经研究了在铜 (I) 或铜 (II) 盐和叔胺的存在下,从二芳基和二烷基二硫代缩醛中消除芳烃和烷硫醇,分别生成相应的芳基和烷基乙烯基硫化物。使用 2 mol 当量的组合。CuCl2 和 2 mol 当量。N,N-二异丙基乙胺是最有利的。
