Addition with α,β unsaturated carbonyl compounds gives 1,5 dicarbonyl products. This method is very convenient and the compounds obtained can easily be separated. We assume that the role of the salt in these reactions is to activate the silicon atom by anionic coordination to form a pentacoordinated silicon intermediate.
甲硅烷基烯醇醚与羰基化合物的反应通过非均相催化而活化。氟化铯是最好的催化剂。不饱和酮是通过使硅烷基烯醇醚与醛和酮缩合反应直接获得的。1,4与α,β不饱和羰基化合物加成,得到1,5二羰基产物。该方法非常方便,并且可以容易地分离得到的化合物。我们假设盐在这些反应中的作用是通过阴离子配位活化硅原子以形成五配位的硅中间体。
