We communicate here that several classes of cyclopentadienylzirconium alkyls, when adsorbed on alumina, yield highly active catalysts for olefin hydrogenation. The results demonstrate that highly active organozirconium catalysts can be generated on a Lewis acid surface that is also active for methyl group abstraction. Although an absolutely rigorous identification of the catalytically active sites as electrophilic, unsaturated cations cannot be made, the data in combination with supported actinide and model solution studies offer increasingly persuasive support for this description.
