Polyquinone synthesis by dehydrogenation agent 3,3',5,5'-tetra-tert-butyl-4,4'-diphenoquinone

Abstract

In this article a new approach for polyquinone synthesis is proposed: Polymerization of hydroquinone or 1,4-benzoquinone by dehydrogenating agent 3,3',5,5'-tetra-tert-butyl-4,4'-diphenoquinone. Interest to this reaction is emerged from the knowledge of products may have a widespread application, polyquinone due to its π-conjugated structure with redox-active chains and 4,4'-bis(2,6-di-tert-butylphenol) due to good stabilizing efficiency in polymers. The obtained polyquinone was characterized by spectroscopic, elemental, NMR, EPR and GPC methods and its polymerized nature was proved.
