New homogeneous rhenium-based metathesis catalysts as models of the rhenium on alumina heterogeneous catalyst

Abstract

Bis(2,6-di-tert-butyl-4-methylphenoxy)isobutylaluminium reacts with dirhenium heptoxide to give complexes containing aluminium coordinated with perrhenate and 2,6-di-tert-butyl-4-methylphenoxy ligands which are active new catalysts for the metathesis of alkenes.
