铑催化的2-（三异丙基甲硅烷基）乙基芳基-和乙烯基重氮乙酸酯的分解导致Z-烯丙基硅烷的立体选择性形成。该转化被认为是通过甲硅烷基导向的分子内C-H官能化进行的，以形成β-内酯中间体，然后是甲硅烷基活化的二氧化碳挤出。
The rhodium-catalyzed decomposition of 2-(triisopropylsilyl)ethyl aryl- and vinyldiazoacetates results in the stereoselective formation of Z-allylsilanes. The transformation is considered to proceed by silyl-directed intramolecular C-H functionalization to form a beta-lactone intermediate followed by a silyl-activated extrusion of carbon dioxide.
