Electro‐oxidative polymerization of 1,3‐Cyclohexadiene

Abstract

1,3‐Cyclohexadiene is electropolymerized at a lower applied potential, compared with the polymerization of other alkene compounds, to give insoluble polymer film on an electrode. The formed polymer contains a phenylene repeated unit, which is confirmed by IR, 1H‐ and 13C‐NMR spectroscopy. Poly(cyclohexene) produced by the electropolymerization is partially aromatized by the oxidation to form a phenylene unit which is accompanied by an elimination of a proton.

Synthesis of Stannole‐Containing π‐Conjugated Polymers by Post‐Element Transformation of Organotitanium Polymer

“…Compared to the reversible electrochemical oxidation behavior of some mononuclear 3,4‐fused bicyclostannoles as described by Staubitz and coworkers, the electrochemical oxidation of the polymers ( 7a and 7b ) proved not be reversible and their oxidation potentials were a little higher than the 3,4‐fused stannoles presumably due to the absence of the alkyl substituents at the 3,4‐positions. The oxidation peaks observed for the polymers ( 7a and 7b ) are not ascribable to the oxidation of the 2,5‐dialkoxyphenylene components judging from the reported oxidation potentials for p ‐dialkoxybenzenes …”
