摘要：

The complexes [MCl(4)(NNR(2))] (M=Mo,W; R(2)=MePh, Ph(2)), [MoCl(NNR(2))(2)(PPh(3))(2)](+), [ReCl(NNAr)(2)(PPh(3))(2)] (Ar=4-substituted phenyl), [ReCl3(NNR(2))(2)py] (R(2)=Ph(2), PhMe) and [ReNCl2(PMe(2)Ph)(3)] form efficient catalysts for metathesis and ring-opening metathesis polymerisation on activation with alkylating agents such as EtAlCl(2). These show activities comparable with other reported systems and stereochemical selectivity for the ROMP reaction of norbomene. Possible reaction mechanisms are discussed.
