    Abstract

    Abstract Image

    Two silylene nickel carbonyl complexes of composition L·Ni(CO)3 (1) {L = PhC(NtBu)2SiCl} and L′2·Ni(CO)2 (2) { L′ = RSiCl2, R = (1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene)} were prepared by reacting 1 equivalent of Ni(CO)4 with 1 equivalent of heteroleptic chlorosilylene L for 1 and with 2 equivalents of carbene stabilized dichlorosilylene L′ for 2 in toluene at room temperature. Both complexes 1 and 2 were characterized by single-crystal X-ray analysis, NMR and IR spectroscopy, EI-MS spectrometry, and elemental analysis.

    Dedicated to Professor Wolfgang Kaim on the occasion of his 60th birthday.
