以4-氯苯乙酸为起始原料,耦合酯化和还原反应合成了4-氯苯乙醇(1),其结构经1H NMR和MS表征。较适宜的反应条件为:4-氯苯乙酸30 mmol,无水乙醇120 mmol,n(4-氯苯乙酸)∶n(SOCl2)∶n(NaBH4)=1.0∶0.5∶1.6,于室温反应3 h完成酯化反应,产物不经分离直接于75℃反应5 h完成还原反应,1收率高于95%,含量大于99%。
2-(4-Chlorophenyl)ethanol(1) was synthesized by esterification and reduction from 2-(4-chlorophenyl) acetic acid(3). The structure was characterized by ^1H NMR and MS. The appropriate reaction conditions were as follows: 3 was 30 retool, ethanot was 120 retool, n ( 3 ) : n ( SOCl2 ) : n ( NaBH4) was 1.0 : 0.5 : 1.6. The yield of 1 was over 95% by esterification at room temperature for 3 h and reduction at 75℃ for 5 h.
