Abstract

Summary: Pd‐initiated polymerization of alkyl diazoacetates as an effective methodology to prepare carbon‐carbon (CC) main chain polymers bearing a substituent on every main chain carbon is described. (NHC)Pd/borate (NHC = N ‐heterocyclic carbene) systems are efficient at affording high M n polymers. π‐AllylPdCl‐based systems can initiate the polymerization with the number of polymer chain per Pd ratios over 1.0 because of occurrence of chain transfer, capable of affording relatively low M n polymers in high yield. Initiation and termination mechanisms have been proposed for the latter initiating systems, based on the detailed MALDI‐TOF‐MS analyses of the low M n products.
