摘要：

Fluoride-mediated desilylation of the propargylidyne [W(equivalent toCCequivalent toCSiMe(3))(CO)(2){HB(pz)(3)}] (1; pz = pyrazol-1-yl) in the presence of [RhCl(CO)(PPh3)(2)] provides the bimetallic complex [Rh(Cequivalent toCCequivalent toW(CO)(2){HB(pz)(3)})(CO)(PPh3)(2)] (2b), which reacts with iodine to give [Rh(Cequivalent toCCequivalent toW(CO)(2){HB(pz)(3)})I-2(CO)(PPh3)(2)] (3) and with [Fe-2(CO)(9)] to provide [RhFe2(mu-C3W(CO)(2){HB(pz)(3)})-(CO)(10)(PPh3)] (4), a rare example of a tricarbido ligand incorporated within a cluster framework.
