Cyanoacetylenes and cyanoacetylides: Versatile ligands in organometallic chemistry
The nitrile like lone pair of the cyanoacetylene PhC?CCequiv;N (1) has been found to coordinate readily to the Ru(PPh3)2Cp fragment, to give [Ru(Nequiv;CCequiv;CPh)(PPh3)2Cp]PF 6 (2) which may be considered as an “extended” derivative of the more common benzonitrile complex [Ru(Nequiv;CPh)(PPh3) 2Cp]PF6 (3). Reaction of 1 with [Co2(CO) 6(dppm)] readily forms the mu, eta2 complex [Co 2(mu, eta2-PhC2Cequiv;N)(CO) 4(dppm)] (4), which reacts with [RuCl(PPh3)2Cp] to give the mixed metal species [{Co2(mu, eta 2-PhC2Cequiv;N){Ru(PPh3) 2Cp}(CO)4(mu-dppm)}]PF6 (5). The eta 1(N) bonded PhCequiv;CCequiv;N ligand is labile, being displaced by NCMe at ambient temperature to afford [Ru(NCMe)(PPh3) 2Cp]PF6, or by tcne to give trans-[{Ru(PPh 3)2Cp}2(mu-tcne)}][PF6] 2 (9). The metallocyanoacetylide [Ru(Cequiv;CCequiv;N)(PPh 3)2Cp] (6) was prepared by lithiation (BuLi) of [Ru(Cequiv;CH)(PPh3)2Cp] followed by treatment with PhOCN. Coordination of the metal fragments Ru(PPh3)2Cp or Fe(dppe)Cp to the N terminus in 6 occurs readily to give the homo- or hetero-bimetallic cations [{Cp(PPh3) 2Ru}(mu-Cequiv;CCequiv;N){ML2Cp}]+, which were isolated as the PF6 salts [ML2Cp = Ru(PPh 3)2Cp (7); Fe(dppe)Cp (8)]. The crystal structures of 2-5, 7 and 9 are reported. The electrochemical response of these complexes suggests there are considerable electronic interactions between the heterometallic end-caps in 8 through the polarised C3N bridge.
