2-Trimethylsilylalk-2-enylstannanes undergo tin(IV) chloride promoted reactions with aldehydes to give homoallylic alcohols with retention of the 2-trimethylsilyl group. 4-Alkoxy-2-trimethylsilylalk-2-enyl(tributyl)stannane 31 reacts with aldehydes under these conditions with excellent stereoselectivity in favour of the 1,5-syn-(E)-products 32 – 35. Preliminary studies into the chemistry of these vinylsilanes
2-三甲基甲硅烷基链-2-烯基锡烷与氯化锡(IV)促进与醛的反应,得到均丙醇,并保留了2-三甲基甲硅烷基。4-烷氧基-2- trimethylsilylalk -2-烯基(三丁基)锡烷31种发生反应与有利于1,5-优异的立体选择性在这些条件下醛顺- (ë)-products 32 - 35。已经对这些乙烯基硅烷的化学性质进行了初步研究。
