Oxidation of amino esters to imine complexes with chiral high-valent oxoruthenium porphyrins

摘要

The chemical oxidation of amino esters by high valent oxoruthenium porphyrins to give mixed ligated imino ester/amino ester ruthenium( II) porphyrin complexes is described. The same complexes were also obtained by anodic oxidation at a constant potential of the corresponding bis(amino ester) ruthenium(II) porphyrins. The electrochemical data were found consistent with a mechanism involving a Ru(IV) intermediate formed by disproportionation of a Ru(III) species. (C) 1998 Elsevier Science S.A. All rights reserved.
