The reactions of R2SiCH2 (R = Me, Et, or Ph), generated by thermolysis of the corresponding 1,1-disubstituted silacyclobutane at 611°, with a variety of ketones and aldehydes, are described. Two major reaction pathways were observed: olefin formation, postulated to occur via a pseudo Wittig reaction; and silyl enol ether formation. Olefin formation predominated in reactions involving aromatic carbonyls
描述了通过相应的1,1-二取代的硅环丁烷在611°下热解而生成的R 2 Si = CH 2(R = Me,Et或Ph)与各种酮和醛的反应。观察到两个主要的反应途径:烯烃的形成,推测是通过假Wittig反应发生的。与甲硅烷基烯醇醚形成。与涉及以甲硅烷基烯醇醚为主要产物的脂肪族酮的反应相反,在涉及芳族羰基的反应中主要形成烯烃。庚醛反应可得到每种产品可比的产率。
