Preparation, structure and some chemistry of FcCCCCCCRu(dppe)Cp
Journal of Organometallic Chemistry(2007)
摘要
The synthesis of Fc(CC)3Ru(dppe)Cp (2) from Fc(CC)3SiMe3 and RuCl(dppe)Cp is described, together with its reactions with tcne to give the tetracyano-dienyl FcCCCC{C[C(CN)2]}2Ru(dppe)Cp (3) and -cyclobutenylFcCCCC{CCC(CN)2C(CN)2}Ru(dppe)Cp (4), with Co2(μ-dppm)n(CO)8−2n (n=0, 1) to give FcC2{Co2(CO)6}C2{Co2(CO)6}CCRu(dppe)Cp (5) and FcCCCCC2{Co2(μ-dppm)(CO)4}Ru(dppe)Cp (6), respectively, and with Os3(CO)10(NCMe)2 to give Os3{μ3-C2CCCC[Ru(dppe)Cp]}(CO)10 (7). On standing in solution, the latter isomerises to the cyclo-metallated derivative Os3(μ-H){μ3-C[Ru(dppe)Cp]CCC[(η-C5H3)FeCp]}(CO)8 (8).
