Dibromophosphines, RPBr2, are obtained by reaction of tetrabromomethane with 7-substituted 7-phosphanorbornenes in toluene at ca. 100 degrees C. The phosphanorbornenes are obtained in situ by cycloaddition of N-phenylmaleimide with 1-substituted 3,4-di-methylphospholes. The overall reaction sequence shows a good compatibility with functional groups.
