Rapid Synthesis of Substituted Azobenzene Diacyl Chlorides under Ultrasonic Irradiation

Keywords： ultrasonic irradiation , substituted azoaromatic diacid , substituted azobenzene diacly chloride , synthesis

超声辐射下,以偶氮取代苯甲酸为原料,氯化亚砜为氯化剂,合成了8种偶氮取代苯甲酰氯系列产物.与普通加热搅拌法相比,反应时间由12 h缩短至4 h,收率达80%～95%.目标化合物结构经红外光谱、核磁共振和元素分析测试技术得到确证.

With substituted azoaromatic diacid and thionyl chloride as starting materials,eight substituted azobenzene diacyl chlorides were first synthesized under ultrasonic irradiation. Compared with that of conventional heating method,the reaction time was shortened from 12 to 4 h,and the yields were in the range of 80%～95%. The structures of all as-prepared products were characterized by 1H NMR,IR spectra and elemental analysis.
