摘要：

Kinetics for the deposition of tetra(tert-butoxy)zirconium onto oxided Al have been studied using quartz crystal microbalance techniques. A kinetic isotope effect was measured (k(H)/k(D) = 1.6) and is interpreted in terms of a strongly bound transition state for proton transfer from an -OH of the surface to an :O of the alkoxide. The chemical nature of the ligand lost on deprotonation, not necessarily the basicity of that group, is suggested to have a profound effect on the mechanistic course of that process.
