Electrophilic addition of SCl2, SeCl2 and SeCl4 to 2 equivalents of allyl trimethyl silane proceeds regioselectively to give bis[2-chloro-3-(trimethylsilyl)propyl] sulfide, selenide and selenium dichloride, respectively. The reaction with TeCl4 affords only diallyl tellurium dichloride. The structures of the compounds were confirmed by 1H, 13C, 77Se and 125Te NMR techniques.
将SCl 2,SeCl 2和SeCl 4亲电加成至2当量的烯丙基三甲基硅烷,区域选择性地进行,分别得到双[2-氯-3-(三甲基甲硅烷基)丙基]硫化物,硒化物和二氯化硒。与TeCl 4的反应仅产生二烯丙基二氯化碲。化合物的结构通过1 H,13 C,77 Se和125 Te NMR技术确认。
