An efficient Fe(TPP)Cl catalyzed insertionreaction 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
