Our group is looking at reacting bis(bromomethyl)aryl ethers with bisphosphines in hopes of forming new, potentially useful poly(ether)poly(phosphonium) salts (PEPPS). My research involved the synthesis of a new monomer, 1,4-bis(p-bromomethylphenoxy)benzene (1  ). p-Cresol was deprotonated with KOH and then treated with p-dibromobenzene with a copper catalyst to form 1,4-bis(p-tolyloxy)benzene. Bromination with NBS/CCl4 and light was used to form 1  . This monomer was reacted with 1,4-bis(diphenyl)phosphinobenzene (2  ) in toluene to form a new PEPPS, which was characterized by 1H and 31P NMR.
