摘要：

A detailed kinetic study of the phosphate-catalyzed heterolysis of two alpha-hydroxyalkyl-chromium(III) complexes, Cr-CH2OH2+ and Cr-C(CH3)(2)OH2+, for a series of non-participating ligands was performed. Evidence for the formation of phosphate coordinated species is presented. The reported rate and activation parameters demonstrate that the catalytic effect results from trans-labilization effects of the coordinated phosphate, which induces a dissociatively activated heterolysis process.
