| Abstract: | A series of polystyrene supported phosphonium salts with degree of functionality of 0.36-0.62mmol/g were prepared by reacting bromoalkylated resins with tributylphosphine. Theactivity of these catalysts were examined by nucleophilic substitution reactions, such ascyanidation, iodization, and sultide formation. They showed satisfactory catalytic efficiency. |
