Oxidation of copper(I)–olefin complexes in aqueous solution by oxygen and hydrogen peroxide

Abstract

The absorption spectra and formation constants of the complexes of Cu^I with ethylene, isobutene, acrylamide. and allyl alcohol have been measured in aqueous solution. The oxidation of the allyl alcohol and ethylene complexes by O₂ and H₂O₂ has been investigated. In the former case H₂O₂ is a major product, and in the latter epoxide is formed. Reaction mechanisms which account for the observed kinetics and stoicheiometries are discussed.
