Reactivity of a 1:1 copper-oxygen complex: isolation of a Cu(II)-o-iminosemiquinonato species

Chem Commun (Camb). 2005 Apr 21:(15):2014-6. doi: 10.1039/b418939f. Epub 2005 Feb 24.

Abstract

While a 1:1 Cu-O2 adduct is generally unreactive with organic substrates, phosphines displace O2 via an associative process and added Cu(I) leads to a novel internal ligand oxidation to yield a Cu(II)-o-iminosemiquinone complex.
