Synthesis of monomers and polymers by the Heck reaction

Abstract

Abstract The Heck reaction allows the synthesis of monomers in a one‐step reaction. Catalyzed by Pd, bromoarenes are reacted with ethylene to form substituted styrenes and symmetrical stilbenes. Unsymmetrical stilbenes are obtained from substituted bromoarenes and styrenes. Substituted hydroquinones and terephthalic acids are also available in high yields. Poly(1,4‐phenylenevinylene) is obtained starting from 4‐bromostyrene.
