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[1,2]。Reeves[3]和Idoux[4]曾用氯甲基聚苯乙烯树脂经多步反应制得催化剂。Tomoi通过CF3SO3H催化ω-溴代烯烃与树脂付-克烷基化反应制得溴烃基树脂,再与三烃基膦反应制成高分子负载季磷盐催化剂, 具有良好的相转移催化效应。

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
