The mononuclear complex [Ru(CO)(4)(C(2)H(4))] (1) reacts with bidentate phosphines to yield the corresponding [Ru(CO)(4)(eta(1)-bidentate phosphine)] (3) complex in quantitative yield thereby offering a new route to this class of compound. Broadband UV photolysis of dichloromethane solutions of the 1,2-bis(diphenylphosphino)propane (dppp) complex [Ru(CO)(4)(eta(1)-dppp)] (3d) under an atmosphere of ethene yields the di-substituted complex [Ru(CO)(3)(eta(1)-dppp)(eta(2)-C(2)H(4))] (9d) in quantitative yield. Both 3d and 9d show potential in selective cluster capping reactions as illustrated by their reactivity with [Ru(5)C(CO)(15)] (4) and [Ru(3)(CO)(12)] (2). (C) 1997 Elsevier Science S.A.
