Summary A cyclic phosphonite(1) was copolymerized with 4, 4′-diphenoquinones (2a–2c) to give 1∶1 alternating copolymers (3a–3c) consisting of a carboxylic acid ester and a triaryl phosphonate ester. Copolymerization took place without added initiator. During the reaction 1 was oxidized whereas 2 was reduced (“redox copolymerization”). A mechanism involving a genetic zwitterion intermediate (4) is proposed for the copolymerization.
