将[N(Bu)_4]Br或FeCl_3-PEG-400作为相转移催化剂,应用于α-氯代烷基烷基醚与无水乙酸钠(或无水甲酸钠)之间的亲核取代反应,以合成具有RCOOCHR′OR″型结构的羧酸醚酯类香料化合物,产物产率可提高10％。中间化合物与产物的结构均经IR,NMR与元素分析证实
The [N (Bu) _4] Br or FeCl_3-PEG-400 was used as a phase transfer catalyst for the nucleophilic substitution reaction between α-chloroalkyl alkyl ether and anhydrous sodium acetate (or anhydrous sodium formate) In order to synthesize the carboxylic ether ester perfume compounds with the structure of RCOOCHR’OR ", the product yield can be increased by 10% .The structures of the intermediate compounds and the products were confirmed by IR, NMR and elemental analysis
