Preparation, structure and some chemistry of FcC[identically equal to]CC[identically equal to]CC[identically equal to]CRu(dppe)Cp
- UWA
The synthesis of Fc(C{triple_bond}C){sub 3}Ru(dppe)Cp (2) from Fc(C{triple_bond}C){sub 3}SiMe{sub 3} and RuCl(dppe)Cp is described, together with its reactions with tcne to give the tetracyano-dienyl FcC{triple_bond}CC{triple_bond}C{l_brace}C[{triple_bond}C(CN){sub 2}]{r_brace}{sub 2}Ru(dppe)Cp (3) and -cyclobutenyl FcC{triple_bond}CC{triple_bond}C{l_brace}C{triple_bond}CC(CN){sub 2}C(CN){sub 2}{r_brace}Ru(dppe)Cp (4), with Co{sub 2}({mu}-dppm){sub n}(CO){sub 8-2n} (n = 0, 1) to give FcC{sub 2}{l_brace}Co{sub 2}(CO){sub 6}{r_brace}C{sub 2}{l_brace}Co{sub 2}(CO){sub 6}{r_brace}CCRu(dppe)Cp (5) and FcC{triple_bond}CC{triple_bond}CC{sub 2}{l_brace}Co{sub 2}({mu}-dppm)(CO){sub 4}{r_brace}Ru(dppe)Cp (6), respectively, and with Os{sub 3}(CO){sub 10}(NCMe){sub 2} to give Os{sub 3}{l_brace}{mu}{sub 3}-C{sub 2}C{triple_bond}CC{triple_bond}C[Ru(dppe)Cp]{r_brace}(CO){sub 10} (7). On standing in solution, the latter isomerises to the cyclo-metallated derivative Os{sub 3}({mu}-H){l_brace}{mu}{sub 3}-C[Ru(dppe)Cp]CCC[({eta}-C{sub 5}H{sub 3})FeCp]{r_brace}(CO){sub 8} (8). X-ray structural determinations of 1, 2, 6 and 7 are reported.
