本文首次报道聚苯乙烯固载聚乙二醇作为三相催化剂在假性紫罗兰酮的合成、丙二酸亚异丙酯的二烃基化及乙酰苯胺、吗啉、哌啶的烃基化中的应用。聚苯乙烯固载聚乙二醇是液—固—固或固—液—液体系的有效三相催化剂。
This paper firstly reports the application of polystyrene immobilized polyethylene glycol as a three-phase catalyst in the synthesis of pseudoionone, the dialkylation of isopropylidene malonate and the alkylation of acetanilide, morpholine and piperidine . Polystyrene supported polyethylene glycols are effective three-phase catalysts for liquid-solid-solid or solid-liquid-liquid systems.
