Abstract

The synthesis of Fc(C=C)(3)Ru(dppe)Cp (2) from Fc(C=C)(3)SiMe3 and RuCl(dppe)Cp is described, together with its reactions with tcne to give the tetracyano-dienyl FcC equivalent to CC equivalent to C (C[=C(CN)(2)]}(2)Ru(dppe)Cp (3) and -cyclobutenyl FcC equivalent to CC equivalent to C{C=CC(CN)(2)C(CN)(2)}- Ru(dppe)Cp (4), with Co-2(mu-dppm)(n)(CO)(8-2n) (n=0, 1) to give FcC(2)(Co-2(CO)(6))C-2{Co-2(CO)(6)}C equivalent to CRu(dppe)Cp (5) and FcC equivalent to CC equivalent to CC2{Co-2(mu-dppm)(CO)(4)}Ru(dppe)Cp (6), respectively, and with Os-3(CO)(10)(NCMe)(2) to give Os-3(mu(3)-C2C equivalent to CC equivalent to C[Ru(dppe)Cp]}(CO)(10) (7). On standing in solution, the latter isomerises to the cyclo-metallated derivative Os-3(mu-H){mu(3)-C[Ru(dppe)Cp]CCC[(eta-C5H3)FeCp]}(CO)(8) (8). X-ray structural determinations of 1, 2, 6 and 7 are reported. (c) 2007 Elsevier B.V. All rights reserved.
