For example, the following have been observed: (i) The increase in steric bulk of the phosphine ligand enhances the metathesis reactivity of 1 (ref 1c). (ii) The presence of excess phosphine slows down the rate of metathesis, and the rate of the reaction was greatly accelerated when one of the phosphines was removed by complexing with copper chloride

The general decomposition pathways for alkylidene complexes usually involve (i) rearrangement of alkylidenes to olefins (for Nb and Ta). (ii) rearrangement of metallacyclobutane to olefins via β-hydride elimination, and (iii) bimolecular coupling of alkylidenes to give olefins. For detail discussions, see
