The reaction of trialkylsilyl- and trialkylgermyl-ketenes with trialkylsilyldiazomethanes proceeds stereoselectively to give one of two feasible stereoisomers, the Z-2,3-bis(Si,Ge)-substituted cyclopropanone. The addition of nucleophilic reagents such as benzyl alcohol, LiAlH4 or (trimethylsilyl)dialkylphosphites is highly stereoselective and is a convenient method for assigning the stereochemical
三烷基甲硅烷基-和三烷基甲锗烷基-烯酮与三烷基甲硅烷基重氮甲烷的反应选择性进行立体反应,得到两种可行的立体异构体之一,Z -2,3-双(Si,Ge)-取代的环丙烷酮。亲核试剂如苄醇,LiAlH 4或(三甲基甲硅烷基)二烷基亚磷酸酯的添加是高度立体选择性的,并且是分配2,3-取代的环丙烷的立体化学构型的方便方法。
