Abstract

Silica-supported tantalum and tungsten hydrides present unusual properties in the activation of alkanes. They activate the C-H bonds of cycloalkanes to form the corresponding surface metal-cycloalkyl complexes. They catalyse the metathesis reaction of alkanes which is an unprecedented process affording the formation of higher and lower homologues. They also catalyse the hydrogenolysis of alkanes and especially ethane which cannot be cleaved by the corresponding group-4 metal hydrides.
