新型单杂环偶氮化合物的合成

Synthesis of Novel Single Heterocylic azo-dyes

本文以氨基硫脲、丙酸、苯甲酸、对硝基苯甲酸为原料制得中间体2-氨基-5-取代-1,3,4-噻二唑,经重氮化后与苯酚、H酸钠盐在冰盐浴条件下反应偶合制得四种新型单杂环偶氮化合物,期望得到新性能的染料.这些新化合物经元素分析,IR确证结构.

This paper indicates that the intermediates 2-amino-5-substituted-1,3,4 thiadiazole were synthesized with aminothourea, metacetonic acid, benzoic acid and paranitrobenzoic acid. After diazotization, they reacted with phenols and H acid in cryosel bath to obtain four new kinds single hetercycle azocompounds. The structures of all novel compounds were confirmed by elemental analysis and IR analysis.
