Transition metal alkynyl complexes by transmetallation from Au(C CAr)(PPh3) (Ar = C6H5 or C6H4Me-4)

Facile acetylide transfer reactions take place between gold(I) complexes Au(C CAr)(PPh3) (Ar = C6H5 or C6H4Me-4) and a variety of representative inorganic and organometallic complexes MXLn (M = metal, X = halide, L-n = supporting ligands) featuring metals from groups 8-11, to afford the corresponding metal-alkynyl complexes M(C CR)L-n in modest to good yield. Reaction products have been characterised by spectroscopic methods, and molecular structure determinations are reported for Fe(C CC6H4Me-4)(dppe)Cp, Ru(C CC6H4Me-4)(dppe)Cp*, Ru(C CC6F5)(eta(2)-O-2)(PPh3)Cp*, Ir(C CC6H4Me-4)(eta(2)-O-2)(CO)(PPh3)(2), Ni(C CC6H4Me-4)(PPh3)Cp and trans-Pt(C CAr)(2)L-2 (Ar=C6H5, L=PPh3; Ar=C6H4Me-4, L=PPh3, PMe3).
