Ring-opened products have been isolated, and evidence has been accumulated indicating that ring opening and hydride displacement occur at competitive rates. No epimerization of I occurs during the course of the reaction. Kinetic and stereochemical results are discussed in terms of the mechanism of hydride displacement from the silacyclobutane ring and from acyclic silicon hydrides. A mechanism involving rate-determining
1,2-二甲基-1-硅环丁烷(I)的几何异构体已在碱性甲醇水溶液中进行了溶剂分解。已经分离出开环产物,并且已经积累了证据表明开环和氢化物置换以有竞争力的速率发生。在反应过程中没有发生I的差向异构。从硅杂环丁烷环和无环氢化硅的氢化物置换机理出发,讨论了动力学和立体化学结果。对于前者而言,涉及确定速率的五价中间体形成的机理是优选的。讨论了许多溶剂分解产物的质谱数据。
