1，1，3-三甲基-3-苯基茚满的催化合成

Catalytic synthesis of 1,1,3-trimethyl-3-phenylindan

本文研究了在酸性离子液体的催化作用下α-甲基苯乙烯二聚合成1,1,3-三甲基-3-苯基茚满。实验结果表明,在无溶剂的条件下室温离子液体(CH_3CH_2)_3NHCl-AlCl_3对该反应具有很高的催化活性和目标产物的选择性,反应进行到5min即可达到100%的α-甲基苯乙烯转化率和97%的环状二聚物1,1,3-三甲基-3-苯基茚满的选择性。

Synthesis of 1,1,3 -trimethyl- 3 -phenylindan catalyzed by acidic ionic liquid was investigated. The results showed that the room temperature ionic liquid （CH3 CH2 ）3 NHCl -AlCl3 possesses high catalytic activity to this dimerization and selectivity to the target product without any organic solvents. The conversion of 100% and selectivity of 97.3% to 1,1,3 -trimethyl- 3 - phenylindan were achieved, respectively.
