The reaction, in the presence of soluble lithium salts, of non-stabilized ylides at low temperature with aliphatic derivatives of acylsilanes gives moderate to good (37–82%) yields of Z-1,2-disubstituted vinylsilanes in excellent (96%) isomeric purities for normal alkyl derivatives. Implications of these results on the mechanistic aspects of the Wittig olefination are discussed
在低温下,不稳定的烷基化物与可溶性硅烷盐的脂族衍生物在可溶性锂盐存在下的反应,可产生中度至良好(37-82%)的Z-1,2-二取代乙烯基硅烷,产率极佳(96%)常规烷基衍生物的异构体纯度。讨论了这些结果对Wittig烯烃化机理的影响。
