Halidometal complexes bearing monodentate N-heterocyclic carbenes [MX2(R-2-bimy)(2)] {bimy = benzimidazole-2-ylidene; R = iPr, M = Pd or Ni, X = I; R = nBu, M = Pd, X = I and R = nBu, M = Ni, X = Br (1)} react under mild conditions with Li[P(SiMe3)(2)], in a 1:1 ratio, to provide the halido(silylphosphido)metal complexes [PdI(iPr(2)-bimy)(2){P(SiMe3)(2)}] (2), [PdI(nBu(2)-bimy)(2){P(SiMe3)(2)}] (3), [NiI(iPr(2)-bimy)(2){P(SiMe3)(2)}] (4) and [NiBr(nBu(2)-bimy)(2){P(SiMe3)(2)}] (5). Cleavage of the P-Si bonds in 3 and 5 with benzoyl chloride leads to the formation of the new (dibenzoylphosphido)halidometal complexes [PdI(iPr(2)-bimy)(2)P{C(O)Ph}(2)] (6) and [NiI(iPr(2)-bimy)(2){P(C(O)Ph)(2)}] (7), respectively. NMR spectroscopy, X-ray crystallography and mass spectrometry are used to analyze these coordination complexes.
