摘要：

Oxo, imido and alkylidene ligand-exchange reactions occur readily between the co-ordinatively unsaturated centres of MQ2X2 (M = Mo or W; Q = 0, NR or CHR'; X = OBu(t)) and M(eta-C5R"5)QX2 (M = Nb or Ta; Q = NR or CHR'; X = Cl or OBu(t)) compounds (R = C6H3Pr(i)2-2,6, R' = CMe2Ph or Bu(t), R" = H or Me); a kinetic study of the reaction between MoO2(OBu(t))2 and Mo(NR) 2(OBu(t))2 indicates that the exchange proceeds via a four-centre transition state.
