ABSTRACT An efficient methodology has been developed for the synthesis of 1,2,4-triazolidine-3-thione and 3-ethoxy-5-phenyl-4H-1,2,4 triazole using N,N-dimethylpyridine-4-amine (DMAP). Aldehydes and thiosemicarbazide were reacted in water at ambient temperature in presence of DMAP and provided corresponding products in good to moderate yield. GRAPHICAL ABSTRACT
摘要 开发了一种使用 N,N-二甲基吡啶-4-胺合成 1,2,4-三唑烷-3-硫酮和 3-乙氧基-5-苯基-4H-1,2,4 三唑的有效方法( DMAP)。醛和氨基硫脲在环境温度下在 DMAP 存在下在水中反应,并以良好至中等产率提供相应的产物。图形概要
