摘要：

Dimeric or monomeric imido complexes of Mo(IV) or W(IV) will slowly catalyze some olefin metathesis reactions, although it is estimated that < 2% of the d(2) species is "activated" by the olefin. An ethylene adduct of {W(NAr')[OCMe2(CF3)](2)}(2) can be isolated, which upon heating is transformed into a new dimeric species that contains an ethyl group and a CH activated ortho methyl group in the NAr' ligand.
