Sandip Murarka and Prof. Dr. Armido Studer Radical/Anionic SRN1-Type Polymerization for Preparation of Oligoarenes Angewandte Chemie International Edition 51
Radicals and anions: The TEMPO-mediated oxidation of magnesiated iodoarenes A provides highly regioregular poly(m-phenylenes) by strictly alternating anionic/radical cross-over chain-growth polymerization. Poly(m-phenylenes) with mean molecular weight (Mn) of up to 20 000 g mol−1 can be prepared under mild conditions by this method. The approach is a new concept for transition-metal-free polyarene synthesis. TEMPO=2,2,6,6-tetramethylpiperidine-N-oxyl radical.
