Transition-Metal Silyl Complexes, 26. - Gold(I) Silyl Complexes

Complexes of type L-Au-SiR3 with L = PR'3 or PhNC and SiR3 = Si(aryl)3, Si(SiMe3)3, or SiPh2Me are prepared by reaction of L-Au-Cl with LiSiR3.Depending on L and R, their stability decreases in the order R'3P-Au-Si(aryl)3 > R'3P-Au-Si(SiMe3)3 > R'3P-Au-SiPh2Me ca.PhNC-Au-SiR3.Reaction of R'3P-Au-CH3 or R'3P-Au-OAc with HSiR3 does not yield silyl complexes.However, using chlorinated silanes like HSiR2Cl, CH3/Cl or OAc/Cl exchange takes place.The Moessbauer spectrum of MePh2P-Au-SiPh3 (6) and NMR- and IR-spectroscopic investigations show that silyl groups act as strong ? donors towards the gold atom.MePh2P-Au-SiPh3 (6) and MePh2P-Au-Si(SiMe3)3 (7) have been characterized by X-ray structure analyses .The Au-Si bond in MePh2P-Au-SiPh2Tol (5) is cleaved by X2 (X = Cl, Br, I), HCl or MeI, but not by H2O or MeOH. - Keywords: Gold(I) silyl complexes / Transition-metal silyl complexes
