Evidence for reversible α-hydrogen abstraction from methyl-cobalt and -rhodium complexes involving the possible formation of hydrido-carbene intermediates
Abstract
Evidence for a reversible α-hydrogen abstraction from methyl groups of CoCH3(PPh3)3 and RhCH3(PPh3)3 involving intermediate carbene-hydride formation is presented on the basis of the mass spectrometric analysis of polydeuteriated methanes formed in the reaction of D2 with CoCH3(PPh3)3 and RhCH3(PPh3) in toluene.
