An efficient, mild, and environment‐friendly methodology for the synthesis of azomethine chromophores through the reaction of 2‐aminobenzonitrile derivatives and acetophenones has been developed using CuCl (10 mol %) catalyst and toluene as a solvent under visible light irradiation. The reaction proceeds readily at room temperature under 20 W white LED with good to excellent yields in short reaction time. This methodology shows significant advantages such as environmentally benign reaction conditions, sustainability, enumerating tolerance of wide range of functional groups, cost‐effectiveness, high atom economy, short reaction time, and applicability for large‐scale synthesis.

可见光诱导的铜催化2-氨基苯甲腈衍生物和苯乙酮席夫碱的合成

通过在可见光照射下使用CuCl（10 mol％）催化剂和甲苯作为溶剂，开发了一种通过2-氨基苯甲腈衍生物与苯乙酮反应合成甲亚胺发色团的高效，温和和环境友好的方法。该反应在室温下于20 W白光LED下容易进行，并且在短时间内即可获得良好至极好的收率。该方法学显示出显着的优势，例如环境友好的反应条件，可持续性，对各种官能团的耐受性，成本效益，高原子经济性，较短的反应时间以及大规模合成的适用性。
