Facile acetylide transfer reactions take place between gold(I) complexes Au(C[triple bond]CAr)(PPh3) (Ar = C6H5 or C6H4Me-4) and a variety of representative inorganic and organometallic complexes MXL, (M = metal, X = halide, L, = supporting ligands) featuring metals from groups 8-11, to afford the corresponding metal-alkynyl complexes M(C[triple bond]CR)Ln in modest to good yield. Reaction products have been characterised by spectroscopic methods, and molecular structure determinations are reported for Fe(C[triple bond]CC6H4Me-4)(dppe)Cp, Ru(C[triple bond]CC6H4Me-4)(dppe)Cp*, Ru(C=CCsF,)(l2-O2)(PPh3)Cp*, Ir(C-CC6H4Me-4)(eta2-O2)(CO)(PPh3), Ni(C[triple bond]CC6H4Me-4)(PPh3)Cp and trans-Pt(C[triple bond]CAr)2L2 (Ar = C6H5, L = PPh3; Ar = C6H4Me-4, L = PPh3, PMe3).
在金（I）配合物Au（C≡CAr）（PPh₃）（Ar = C₆H₅或C₆H₄Me - 4）与各种具有代表性的无机和有机金属配合物MXL（M =金属，X =卤化物，L =辅助配体）之间发生了简便的乙炔基转移反应，这些配合物中的金属来自8 - 11族，反应以中等至良好的产率得到相应的金属炔基配合物M（C≡CR）Ln。反应产物已通过光谱方法进行了表征，并报道了Fe（C≡CC₆H₄Me - 4）（dppe）Cp、Ru（C≡CC₆H₄Me - 4）（dppe）Cp*、Ru（C≡CC₅F₅）（μ₂ - O₂）（PPh₃）Cp*、Ir（C≡CC₆H₄Me - 4）（η² - O₂）（CO）（PPh₃）、Ni（C≡CC₆H₄Me - 4）（PPh₃）Cp和反式 - Pt（C≡CAr）₂L₂（Ar = C₆H₅，L = PPh₃；Ar = C₆H₄Me - 4，L = PPh₃，PMe₃）的分子结构测定结果。
