Facile Access to Transition-Metal-Carbonyl Complexes with an Amidinate-Stabilized Chlorosilylene Ligand

Three transition-metalcarbonyl complexes [V(L)(CO)3(Cp)] (1), [Co(L)(CO)(Cp)] (2), and [Co(L2)(CO)3]+[CoCO)4]- (3), each containing stable N-heterocyclic-chlorosilylene ligands (L; L=PhC(NtBu)2SiCl) were synthesized from [V(CO)4(Cp)], [Co(CO)2(Cp)], and Co2(CO)8, respectively. Complexes 13 were characterized by NMR and IR spectroscopy, EI-MS spectrometry, and elemental analysis. The molecular structures of compounds 13 were determined by single-crystal X-ray diffraction.
