The acylation of isobutylbenzene by using catalytic amount of Bi(OTf) 3 has been investigated as function of reaction time, reaction temperature, catalyst dosage and acetyl chloride.
对乙酰基异丁基苯是合成镇痛药Ibuprofen的重要中间体 ,工业上合成这种中间体一般采用催化剂为AlCl3,除了用量大以外 ,使用AlCl3存在一系列的问题[1 ] :( 1 )产物的选择性差 ;( 2 )自身有腐蚀性 ,对设备的腐蚀相当严重 ;( 3)遇水迅速分解 ,释放出大量的氯化氢气体 ,对环境污染严重。
Especially the environmentally friendly recovery of catalyst and the asymmetric carbonylation of p-isobutylstyrene for preparing ibuprofen are reviewed.
