A general, green, and scalable synthesis of the useful imines and α,β-unsaturated imines is successfully achieved by a low-loading and powerful, mild and efficient copper-catalyzed aerobic oxidative reaction of alcohols and amines in the open air at room temperature under base- and dehydrating reagent-free conditions. This practical reaction can use air as the economic and green oxidant, tolerates
有用的亚胺和α,β-不饱和亚胺的常规,绿色和可扩展合成方法是通过在室温下在室外空气中进行低负荷,强力,温和有效的铜催化的醇和胺的需氧氧化反应而成功实现的在无碱和无脱水试剂的条件下。该实际反应可以使用空气作为经济的绿色氧化剂,可以耐受多种底物,可以大规模提供高产率的目标亚胺,并且产生水作为唯一的副产物,因此是最佳的胺化方法尚未直接使用酒精和胺。
