sium chlorides of the general formula Me3-n(t-BuO)nSiCH2MgCl, n = 1–3, with some organotin and organosilicon monochlorides has been studied. It has been found that the reaction of the Grignard reagents with trialkyltin chlorides readily proceeds via the methylene carbon with the formation of C-substituted products Me3-n(t-BuO)nSiCH2SnR3, R = Me, n-Bu in high yields. The path of this reaction with Me3SiCl
摘要研究了通式为Me3-n(t-BuO)nSiCH2MgCl的(叔丁氧基甲硅烷基)甲基氯化镁与一些有机锡和有机硅一氯化物之间的相互作用。已经发现格氏试剂与三烷基锡氯化物的反应易于通过亚甲基碳进行,并以高收率形成了C-取代的产物Me3-n(t-BuO)nSiCH2SnR3,R = Me,n-Bu。与Me3SiCl和MePh2SiCl的反应路径取决于格利雅(Grignard)化合物的结构和氯硅烷的亲电性。出乎意料地发现,格氏试剂中叔丁氧基的增加导致形成Me3-n(t-BuO)nSiCH2OSiMeR2,R = Me,Ph,反应产物中有机甲硅烷基甲基硅化合物的含量降低。
