Abstract

High Catalytic Activity Homogeneous Catalysis Inorganic Oxide Reductive Elimination Surface Complex
The reaction between Schrock-type W alkylidyne complexes and inorganic oxides leads to several surface complexes, at least one of them bearing an alkylidene ligand. In the case of W(CCMe3)Np3/Nb2O5, the high catalytic activity seems to be more related to the reaction of a reduced W-species with the olefin via a π-allyl mechanism than to the presence of the alkylidene ligand itself.
