Mechanisms of Reactions Related to Selective Aikane Oxidation by Pt Complexes

摘要

Some of the most promising homogeneous systems for the selective activation and functionalization of alkanes are based on platinum. Proposed key reaction steps at Pt(II) and Pt(IV) metal centers have been directly observed and studied using model compounds. Investigations of oxidative addition and reductive elimination reactions of carbon-hydrogen, carbon-carbon and carbon-heteroatom bonds have provided detailed information about the intermediates and kinetic barriers involved in these bond cleavage and formation reactions. In addition, reactions of platinum alkyl complexes with dioxygen, an ideal oxidant for aikane functionalization, have been studied.
