The reactions of [RuHX(PPh3)3] (X = Cl, O2CMe) and [MHCl(CO)(PPh3)3] (M = Ru, Os) with 1,1-diphenylprop-2-yn-1-ol provide convenient access to alkynyl, alkenyl, propenylidene, and acetoxyallenyl complexes of divalent ruthenium and osmium, including [RuCl2(=CHCH= CPh2)(PPh3)2] and the complexes [Ru(C=CCPh2OH)-(O2CMe)(CA)2(PPh 3)2] (A = NCMe3, O), protonation (HPF6) of which provides [Ru(O2CMe)(=C=C=CPh2)-(CNCMe3) 2(PPh3)2]PF6 or the metallacycle [Ru{κ2C,O-C(=C=CPh2)O2CMe}(CO) 2(PPh3)2]PF6, respectively.
