Chemistry of Ruthenium and Rhodium Eta(4)-Thiophene Complexes

Reduction of ($(\eta\sp6$-$\rm C\sb6Me\sb6)Ru(\eta\sp5$-C$\sb4$R$\sb4$S)) (OTf)$\sb2$(C$\sb4$R$\sb4$S = C$\sb4$H$\sb4$S (1a), 2,5-Me$\sb2$C$\sb4$H$\sb2$S (1b), and 2,3,4,5-Me$\sb4$C$\sb4$S (1c)) and (($\eta\sp5$-C$\sb4$Me$\sb4$S)$\sb2$Ru) (OTf)$\sb2$ (1d) with Cp$\sb2$Co produces (arene)Ru($\eta\sp4$-C$\sb4$R$\sb4$S) (2a-d). 2d is unstable $>-20\sp\circ$C. It reacts with Fe(CO)$\sb5$ in the presence of Me$\sb3$NO to yield the thermally stable $(\eta\sp5$-$\rm C\sb4Me\sb4S)Ru(\eta\sp4{:}\eta\sp1$-$\rm C\sb4Me\sb4S)Fe(CO)\sb4$(2d$\cdot$Fe(CO)$\sb4).$
