The goal of this research was to study the reaction of bisphosphines, bis(diphenylphosphino)acetylene and bis(diphenylphosphino)butane, with a,a'-dibromo-p-xylene to produce polyphosphonium salts, (3a) and (3b). Polymers containing phosphorus-carbon bonds and phosphocation centers have generated some interest in recent years, in part, due to their ability to function as anion exchange resins. Comparison of polymer NMR spectra (DMSO-d6) to smaller model compounds, prepared by reacting benzyl bromide (PhCH2Br) and bisphosphines, allowed assignment of 1H and 31P NMR resonances.
