An efficient Fe(TPP)Cl catalyzed insertion reaction of in situ generated benzylic carbenes from N-tosylhydrazones into X–H (X = Si, Sn, Ge) was developed. Silanes bearing tertiary, secondary, and primary (3°, 2°, and 1°) Si–H bonds all reacted well to afford insertion products in moderate to high yields (up to 97%), and the reaction time could be significantly shortened to 1 h under microwave irradiation
开发了一种有效的Fe(TPP)Cl催化的原位生成的苄基卡宾从N-甲苯磺酰into插入X–H(X = Si,Sn,Ge)的插入反应。带有叔,仲和伯(3°,2°和1°)Si-H键的硅烷都能很好地反应,从而以中等至高产率(高达97%)提供插入产物,并且反应时间可以大大缩短在微波照射下至1小时。开发了一种可编程的逐步双插入策略,用于合成不对称的四取代的硅烷。
