Palladium-catalyzed carbene coupling polymerization: synthesis of -poly(arylene vinylene)s

The Pd-catalyzed carbene coupling reaction of N -tosylhydrazones and benzyl bromides has been developed into a polymerization process for the first time, providing an efficient method for the synthesis of poly(arylene vinylene)s (PAVs).

Description
Summary:The Pd-catalyzed carbene coupling reaction of N -tosylhydrazones and benzyl bromides has been developed into a polymerization process for the first time, providing an efficient method for the synthesis of poly(arylene vinylene)s (PAVs). This method affords PAVs bearing E -vinylene units predominantly. It can also introduce a CF 3 group on each vinylene carbon atom in the polymer main chain. The polymerization has a broad scope and the resultant polymers exhibit interesting optical properties and good thermal stabilities. A new method to access poly(arylene vinylene)s (PAVs) has been developed. The method is based on Pd-catalyzed carbene coupling reaction of N -tosylhydrazones and benzyl bromides.
