Facile access to transition-metal-carbonyl complexes with an amidinate-stabilized chlorosilylene ligand.

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