Abstract
Thermolysis of Ru(IEt2Me2)(PPh3)2(CO)H2 (1) (IEt2Me2 = 1,3-bis(ethyl)-4,5-dimethylimidazol-2-ylidene) in the presence of CH2:CHSiMe3 resulted in C-H activation of an NCH2CH2-H bond, loss of the proton, and metalation giving Ru(IEt2Me2)'(PPh3)2(CO)H2 (2). The process can be reversed by H2 and alcs. giving different isomers of the starting dihydride complex 1. The crystal structure of 1, where the IEt2Me2 ligand is trans to the hydride, is presented as well as the structure of complex 2.
