time at 457.9 nm using a CW argon ion laser. The kinetics of reactions of ClSiH with C2H4, CH2CHCMe3, C2H2, Me2O, SO2, HCl, MeSiH3, Me2SiH2, Me3SiH, MeGeH3, Me2GeH2 and precursor have been studied at ambient temperatures for the first time. Addition reactions of ClSiH and reactions with lone pair donors are faster than insertion reactions. Surprisingly ClSiH inserts faster into Si–H than Ge–H bonds
通过在气相中通过1-nm-1-silacyclopent-3-ene的193 nm激光快速光解法制备亚甲叉基(ClSiH)。使用CW氩离子激光器在457.9 nm处实时监测ClSiH。ClSiH与C 2 H 4,CH 2 CHCMe 3,C 2 H 2,Me 2 O,SO 2,HCl,MeSiH 3,Me 2 SiH 2,Me 3 SiH,MeGeH 3,Me 2 GeH 2的反应动力学。首次在环境温度下对前驱体和前驱体进行了研究。ClSiH的加成反应和与孤对供体的反应比插入反应更快。出乎意料的是,ClSiH插入到Si–H中的速度比Ge–H键快。ClSiH在SiH 2和SiCl 2之间的反应性中间。ClSiH和SiH 2的相对反应性差异很大。
