摘要：

The bis(mu-thiocarbene) [(cp)(OC)Fe{mu-C(CN)SMe}{mu-C(SMe)X}Fe(cp)](X = H or CN; cp = eta-C5H5) and all the intermediate species obtained from the thiocarbyne derivative cis-[Fe-2(mu-CS){mu-C(SMe)}(CO)(2)(cp)(2)]-[SO3CF3] via mu-C stereoselective addition of X(-), photochemical formation of [(cp)Fe{mu-C(SMe)X}(mu-CS)Fe-(CO)(cp)] followed by stepwise addition of MeSO(3)CF(3) and (NBu(4)(n))CN at the bridging CS group have been prepared and characterized. Attempts to obtain the bis(mu-thiocarbene) [{Fe[mu-C(CN)SMe](CO)(cp)}(2)] failed. The crystal structure of [{Fe[mu-C(CN)SMe](cp)}(2)] which demonstrates the presence of two doubly bridging thiocarbene groups has been determined. The results show that bis(mu-thiocarbene) derivatives are stable when at least one of the ligands acts as a double bridge via a S-Fe bond.
