基于磺酰芳基肼的偶氮类染料的合成

Synthesis of Azo Dyes Based on N'-Tosyl Arylhydrazines

偶氮化合物是一类非常重要的合成染料。本文应用N'-对甲基苯磺酰基芳基肼作为重氮源,在碳酸钾的促进下,与萘酚或N,N-二甲基苯胺在碳酸钾促进下发生偶联合成了系列偶氮类化合物,收率63%~85%,其结构经~1H NMR确证。

Azo compounds are important as synthetic dyes. A series of azo dyes were synthesized by coupling reaction of N＇-tosyl arylhydrazines with naphthol or N,N-dimethylaniline promoted by K2CO3 under mild conditions. The yields were 63% - 85%,and the structures were confirmed by^1H NMR.
