Hafnium-Hydride Complexes Anchored to Silica. Catalysts of the Low Temperature Hydrogenolysis of Alkanes and Hydrogenation of Olefins

Article abstract of DOI:10.1246/cl.1993.1931

Silica grafted hafnium hydride complexes were synthesized from tetra(neopentyl)hafnium and a partially dehydroxylated silica.These surface complexes are catalysts for hydrogenolysis of neopentane and butane and for hydrogenation of isobutene and propene, under mild conditions.Their catalytic properties are compared to the related supported Zr hydride complexes.
