Novel µ-methyl complexes of vanadium and their relevance to bimolecular deactivation of homogeneous imidovanadium polymerisation catalysts
Abstract
Attempted dimethylation of [CpV(NC6H3Pri2-2,6)]Cl2 using Grignard reagents affords novel µ-methyl complexes arising by reductive dimerisation; the structure of one of these products, [CpV(NC6H3Pri2-2,6)(µ-Me)2]2(µ-Mg) 2, reveals V–(µ-Me)–Mg, V–Mg, N–Mg and C–H···Mg interactions.
