摘 要:用微波催化法制備N(xiāo)-(2-吡啶基)鄰苯二甲酰亞胺,考察了功率、時(shí)間、反應物料配比,溶劑等參數,得到優(yōu)化工藝參數為:以N,N-二甲基甲酰胺為溶劑:功率5.0 W,物料比n(2-氨基吡啶)∶n(鄰苯二甲酸酐)=1∶1.2,反應時(shí)間6 min,收率91.3%;無(wú)溶劑時(shí):功率5.0 W,物料比n(2-氨基吡啶)∶n(鄰苯二甲酸酐)=1∶1.2,反應時(shí)間8 min,收率:85.5%。微波催化法具有環(huán)保、時(shí)間短、收率高、后處理簡(jiǎn)單等優(yōu)勢。

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
