Some chemistry of trans-Ru(C triple bar CC triple bar CH)(2)(dppe)(2): Syntheses of bi- and tri-metallic derivatives and cycloaddition of tcne

Abstract

Conventional reactions of trans-Ru(CCCCH) 2(dppe) 2 1 with RuCl(PP)Cp′ or AuCl(PPh 3) have given the complexes trans-Ru(CCCCR)(CCCCR′)(dppe) 2 [R = H, Ru(PP)Cp′, Au(PPh 3); R′ = Ru(PP)Cp′, (PP)Cp′ = (PPh 3) 2Cp, (dppe)Cp, (dppe)Cp (not all combinations)]. The Au(PPh 3) derivatives react with Co(μ 3-CBr)(μ-dppm) (CO) 7 to give trans-Ru(CCCCH){CCCCC[Co 3(μ-dppm)(CO) 7]}(dppe) 2 and trans-Ru{CCCCC[Co 3(μ-dppm) (CO) 7]} 2(dppe) 2, which contain respectively four- and five-carbon and two five-carbon chains linking the metal centres. Also described is the addition of tcne to trans-Ru(CCCCH) 2(dppe) 2 to give the bis(η 1-tetracyanobutadienyl) complex trans-Ru{CCC[C(CN) 2]CHC(CN) 2} 2(dppe) 2 11, of which the single crystal X-ray structure is reported. © 2011 Elsevier B.V.
