Kinetic study of electroch emical generation of diphenylamin e derivatives of catechol

Catech ol is one of the com mon building blocks in organic synthesis and is prod uced in industrial scales as the precursor of pesticides, perfumes and ph armaceuticals. The m ost well-known characteristic of the catechols is that they can be easil y oxidized mainly due to their antioxi dant activity and low oxidation potentials [۱]. The p roducts of oxidation are the corresponding reactive and electron-deficient o-quinones. Co nsidering th eir instability they can be produced o nly by in-s itu methods and mild oxidation of catechols. One of the most successful in-situ generations of reactive o-quinone s species is the electro chemical o xidation. [۲] The Michal a dditions of aliphatic, aromatic, and benzyli c amines to electroch emically generated o-quinone have been reported previously. The reaction pro ducts of aromatic amines with o-quinones have been reported to be d iphenylamine derivatives or their related quinonic forms. Diphenylamine is a parent compound of man y derivatives, which are used for the production of dyes, perfumery, pharmaceuticals, photo graphy ch emicals and further small-scale applica tions [۳].
