Abstract

The reactions of K[HB(pz)3] (pz = pyrazol-1-yl) with the coordinatively unsaturated σ-vinyl complexes [Ru(CRCHR)Cl(CO)(PPh3)2] (R = H, Me, C6H5) proceed with loss of a chloride and a phosphine ligand to provide the compounds [Ru(CRCHR)(CO)(PPh3){HB(pz)3}] in high yield. Similar treatment of the complex [Ru(C6H4Me-4)Cl(CO)(PPh3)2] leads to the related σ-aryl derivative [Ru(C6H4Me-4)(CO)(PPh3){HB(pz)3}] whilst the complex [RuClH(CO)(PPh3)3] treated successively with diphenylbutadiyne and K[HB(pz)3] provides the unusual derivative [Ru{C(CCPh)CHPh}(CO)(PPh3){HB(pz)3}].
