以4-甲基苯酐为原料,合成一系列的具有季铵盐和NHPI双重结构的新型催化剂,并通过元素分析、红外光谱(IR)、核磁共振氢谱(1H NMR)等检测分析手段表征确认新化合物的结构,新型催化剂在催化氧化乙苯方面表现出了良好的催化活性,其中3c使得乙苯转化率达到82.2％,苯乙酮选择性达到88.4％.%A series of NHPI derivatives with the structure of quaternary1 ammonium were synthesized from 5-methylisobenzofuran-l, 3-dione. These new compounds were characterized by elemental analysis,IR and 1H NMR. They all displayed better catalytic activities, especially,the compound 3c behaved 80% conversion of ethylbenzene and 87% selectivity of acetophenone.
