The stereochemistry of attack on an allylsilane is more selective when the substituent on the chiral centre carrying the silyl group is larger than a methyl group, as shown by the reactions of the allylsilanes (5) and (12) with osmium tetroxide, m-chloroperbenzoic acid, and Yamamoto's methylenation reagent.
攻击上的烯丙基硅烷的立体化学是当上的手性中心携带甲硅烷基的取代基不是甲基更大更有选择性,如由烯丙基硅烷(的反应5)和(12)用四氧化锇,米-氯酸和山本的亚甲基化试剂。
