The unsaturated sulfides were prepared from corresponding alkenyl chlorides and sodium methylmercaptide by general procedure. Three new methylmercapto-group-containing organosilicon monomers were prepared from corresponding unsaturated sulfides with trimethoxysilane in the presence of tetrakis（triphenylphosphine）platinum complex as catalyst. Their structures were identified by elemental analysis, IR, 1 H NMR and MS. A possible pathway for the fragmentation of the title monomers under electron bombardment was also suggested. 不饱和硫醚 硅氢加成 四(三苯膦)合铂 含硫有机硅单体 质谱 unsaturated sulfides hydrosilylation tetrakis-（triphenylphosphine） platinum eomplex sulfides-containing organosilicon monomers mass spectra 1990-04-01 2021-04-01 4
