N2 - Reactions between 1,1'-(Me3SiC equivalent to C)(2)Rc' [Rc' = ruthenocen-1, 1'-diyl, Ru(eta-C5H4-)(2)] and RuCl(PP)Cp' in the presence of KF gave 1,1'-{Cp(PP)RuC equivalent to C}(2)Rc' [Cp' = CP, PP = PPh3 1, P(m-tol)(3) 2, dppe 3, dppf 4; Cp' = Cp*, PP = dppe 5]. Compounds 1 and 2 react with tcne to give two diastereomers a/b of the allylic (vinylcarbene) complexes 6 and 7, while methylation of 5 gave the bis-vinylidene [1,1'-{Cp*(dppe)Ru=C=CMe}2Rc'](BPh4)(2) (8). The X-ray structures of 4, 6b and 8 have been determined. Cyclic voltammograms indicate that there is some electronic communication between the ruthenium end-groups through the Rc' centre.
