Selective desulfurization of 2-alkyl-1,3-dithianes, -oxathiolanes, or -thiazolidines 1 with one equivalent of tri-n-butyltin hydride yields acyclic compounds R1R2CHX(CH2)nSSnBu3 (X = S,O,NH; n= 2,3), (2) which can be destannylated to the corresponding mercaptans 3.
用一当量的氢化三正丁基锡对2-烷基-1,3-二硫杂环丁烷,-氧杂硫杂环戊烷或-噻唑烷1进行选择性脱硫,得到无环化合物R 1 R 2 CHX(CH 2)n SSnBu 3(X = S, O,NH; n = 2,3),(2),其可被脱甲锡化为相应的硫醇3。
