Ynamides, though relatively more stable than ynamines, are still moisture-sensitive and prone to hydration especially under acidic and heating conditions. Here we report an environmentally benign, robust protocol to synthesize sulfonamide-based ynamides and arylynamines via Sonogashira coupling reactions in water, using a readily available quaternary ammonium salt as the surfactant.
酰胺虽然相对比氨胺更稳定,但仍然对水分敏感,尤其在酸性和加热条件下易于水合作用。在这里,我们报告了一种环境友好,稳健的方案,该方案通过使用易于获得的季铵盐作为表面活性剂,通过水中的Sonogashira偶联反应,合成基于磺酰胺的乙酰胺和芳基乙胺。
