3-苯丙醛制备

1.由肉桂醛经催化氢化而制得。

2.制法：

于装有搅拌器、温度计、回流冷凝器、通气导管的反应瓶中，加入镁屑2.88g（0.12mol），无水THP300mL，一粒碘。通入干燥的氮气。滴加由β-苯乙基氯（2）14.06g（0.1mol）溶于50mLTHF的溶液，先加入约2mL温热引发反应。当反应引发后，慢慢滴加其余溶液，滴加速度以反应液微微回流为宜。加完后于23℃搅拌反应1h，而后回流反应8h。冷至0℃，慢慢滴加N-甲酰基哌啶13.56g（0.12mol）与干燥的盐酸酸化至PH2，分出有机层，水层用乙醚提取3次。合并有机层，依次用水、10%的碳酸氢钠、饱和食盐水洗涤，无水硫酸镁干燥，回流溶剂后减压分馏，收集约87℃/133Pa的馏分，得3-苯基丙醛（1）8.8～10.2g，收率66%～76%。
