摘要： This invention relates to (organothiomethyl)chlorosilanes and methods for their preparation by the dehydrohalogenative Si—C coupling reaction of oranothiomethyl halides with Si—H containing chlorosilanes (hydrosilanes), wherein a mixture of oranothiomethyl halide and hydrosilane is heated in the presence of tertiary amine or organic salts (quaternary organoammonium and organophosphonium halides to give (organothiomethyl)chlorosilanes, which is existing a sulfur atom in alkyl chain, (formula: R2SCH2SiCl2R1) in good yield. wherein R1 represents a hydrogen atom, halogen, or C1–C6 alkyl; R2 is selected from the group consisting of C1–C6 alkyl or an aryl group. Especially, this reaction using organic salt as a catalyst provide better economical matter and yield compared with conventional methods, because only catalytic amount of organic salt is required and the catalyst can be separated from the reaction mixture and recycled easily.
