aqueous 1,4-dioxane, and of solvolysis of 1-dibromomethyl-1-methylsilacyclobutane in aqueous n-propanol. Possible mechanisms are discussed. A general scheme is proposed for cleavage of SiC bonds, which involves general base and general base—nucleophile catalysis, in which for one class of reagents viz. (α-haloalkyl)triorganosilanes, all the component reactions have been defined.
已经进行了动力学研究,研究了在正丙醇水溶液和1,4-二恶烷水溶液中自发和吡啶催化的(三卤代甲基)三甲基硅烷(Me 3 SiCX 3,X = Cl,Br)的溶剂化,以及1-的溶剂化。正丙醇水溶液中的二溴甲基-1-甲基硅环丁烷。讨论了可能的机制。提出了裂解SiC键的通用方案,该方案涉及通用碱和通用碱-亲核试剂的催化,其中对于一类试剂来说。(α-卤代烷基)三有机硅烷,所有组分反应均已定义。
