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.
Key words: triphase catalyst, phosphonium, phase-transfer catalyst
