Synthesis of Poly(phenylenes) by a Rapid Polymerization of 1-Bromo-4-lithiobenzene Using HMPA

摘要

A synthesis of poly(phenylene) is described by the treatment of 1-bromo-4-lithiobenzene with hexamethylphosphoramide (HMPA). The polymerization occurred nearly instantaneously even at -78 C. Conditions have been optimized using
