effect of the trimethylsilyl group previously observed for trimethylsilylcyclopropane. In contrast cis- and trans-1-trimethylsilyl 2-(trimethylsilylmethyl)cyclopropane undergo facile diacylation with ring opening. This reaction offers a new, competitive acces to bifunctional butenes and especially to diacyl derivatives.
顺式和反式-1,2-双(三甲基甲硅烷基)环丙烷与三甲基甲硅烷基氯磺酸酯或乙酰氯/氯化铝反应,得自由一个三甲基甲硅烷基取代而没有开环的反式-磺酰基或-乙酰基衍生物。结果证实了先前对于三甲基甲硅烷基环丙烷观察到的三甲基甲硅烷基的作用。相反,顺式和反式-1-三甲基甲硅烷基2-(三甲基甲硅烷基甲基)环丙烷经历开环的容易的二酰基化。该反应为双官能丁烯,尤其是二酰基衍生物提供了一种新的竞争性途径。
