Oxidative transformations of some activated aromatic compounds mediated by cobalt ii and copper ii complexes

Abstract

The oxidative polymerisation and hydroxylation reactions of aromatic compounds are biologically important reactions Cobalt complexes are important for oxidative reactions from its relevance to the reactivity of vitamin B12 On the otherhand copper complexes have special interest from their role in enzymes such as Tyrosinase and Galactose oxidase etc They also have direct relevance in biosynthesis through oxidative polymerisation to give lignin that constitutes major component of plants The de
