Abstract:2-(Pyridin-2-yl)isoindoline-1,3-dione was prepared with microwave technology,and the optimal parameters such as power,reactive time and ratio of reaction material were obtained. In the DMF solvent,yield of the product was 91.3% under the optimal conditions of power 5.0 w,ratio 1∶1.2 and reaction time 6 min. In no solvent,the yield of the product was 87.4% under the conditions such as power 5.0 w,ratio 1∶1.2 and reation time 8 min. By contrast,the microwave catalytic technology had the advantages over the environmental compatability,short time,high yield and simple post-treatment.
Key words:2-(pyridin-2-yl)isoindoline-1,3-dione;microwave catalytic;synthesis
