Abstract

Reduction of [Ru(η5-C4Me4S)2](OTf) 2 (C4Me4S is 2,3,4,5-tetramethylthiophene, OTf is CF3SO3-) at -78 °C with 2 equiv of Cp2Co gives Ru(C4Me4S)2 (1), which is stable at <-20°C. DNMR studies suggest that 1 is fluxional as a result of the facile interconversion of η5-C4Me4S and η4-C4Me4S ligands. In contrast, (η5-C4Me4S)Ru{(η41-C4Me4S)Fe(CO)4}, prepared from 1, Fe(CO)5, and Me3NO, is thermally stable and adopts a static structure. In the solid state, 1·Fe(CO)4 adopts a symmetric structure such that the two pairs of C=C groups are eclipsed.
