N-heterocycliccarbene (NHC)-stabilized hydrosilylyne complex Cp*(CO)2WSiH((Me)IMe)2 (3a) ((Me)IMe = 1,3,4,5-tetramethylimidazole-2-ylidene) was formed by the reaction of an NHC-stabilized silylene complex Cp*(CO)2(H)WSiH((Me)IMe)C(SiMe3)3} (2a) with 1 equiv of (Me)IMe at 70 °C. In this reaction, HC(SiMe3)3 was unexpectedly eliminated from 2a. A C5Me4Et analogue of 3a, (C5Me4Et)(CO)2WSiH((Me)IMe)2
