摘要

Abstract Direct dimetalation of 1-methyl-2-(methylthio) benzene (1) gives the dilithiated species (2) in good yield, which can be used to introduce substituents into the thiomethyl and methyl groups. Species 2 can react also with a variety of dichlorosilanes and dichlorostannanes, and with sulphur chloride, to yield derivatives of 1, 3-benzothiasilin, 1, 3- benzothiastannin and 1, 3-benzodithiin respectively. Reaction of 2 with tetrachlorosilane ...
