Abstract
Silica-anchored zirconium hydride complexes have been synthesized by c ontrolled hydrogenolysis of a tris(neopentyl)zirconium surface complex . They have been characterized spectroscopically and their chemical re activity compared to related molecular analogues. The mechanism of the ir formation is discussed. High reactivity and thermal stability seem to be correlated to the presence around Zr of the 'solid' ligand; its influence is discussed in terms of electronic and immobilizing effects .
