摘要
用高分子材料负载季鏻盐相转移催化剂的开发和研究已有报导。Reeves和Idoux曾用氯甲基聚苯乙烯树脂经多步反应制得催化剂。Tomoi通过CF_3SO_3H催化ω-溴代烯烃与树脂付-克烷基化反应制得溴烃基树脂。
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.
