Polymerization of 1-Bromo-4-lithiobenzene in THF. A Route to Soluble Polyphenylenes
Abstract
A synthesis of polyphenylene is described that involves the room temperature polymerization of 1-bromo-4-lithiobenzene in THF. The polymerization was complete within 2 h to afford 65% yield of an ether insoluble fraction of brominated polyphenylene that was soluble in THF, CH2C12 and CHC13. Analysis of the initially formed polymers showed that there was a high bromide content with approximately one bromide for every three aryl rings. Debromination of the material was achieved by treatment with butyllithium and quenching with water. The pre-quenched polymer had no lithiated aromatic rings and LiH appeared to be present in significant amounts upon completion of the polymerization.
