The trimethylchlorosilane/magnesium/hexamethylphosphoric triamide system reacts with various α-ethylenic aldehydes and ketones to give the 1,4-addition compound of two trimethylsilyl groups. This, after hydrolysis, leads to aldehydes and ketones, C-silylated in β position with respect to the carbonyl group. The corresponding alcohols have been prepared.
三甲基氯硅烷/镁/六甲基磷三酰胺体系与各种α-乙烯醛和酮反应,生成两个三甲基甲硅烷基的1,4-加成化合物。在水解之后,这导致醛和酮,相对于羰基在β位上C-甲硅烷基化。已经制备了相应的醇。
