摘要：

Reaction of WL(CO)3C = CPh and Os3(CO)10(C2R2) produced WOs3L(CO)9(mu-3-CPh)(CCRCR), L = Cp, R = Tol (p-MeC6H4) 1a; L = C5Me5, R = Me, 1b; treatment of complexes 1 with ditolylacetylene yielded planar clusters WOs3L(CO)8(mu-3-CPh)[C(Tol)C(Tol)CCRCR], L = Cp, R = Tol, 2a; L = C5Me5, R = Me, 2b; complex 2b underwent reversible loss of CO to produce an unsaturated cluster WOs3C5Me5(CO)7(mu-3-CPh)[CMeCMeCC(Tol)C(Tol)] 3b; thermolysis of 3b in refluxing xylene induced the rearrangement of the cluster core, giving another unsaturated complex 4b with identical molecular formula; complexes 1a, 3b and 4b have been examined by X-ray diffraction studies.
