This paper describes an efficient, sustainable, one-step procedure for synthesizing substituted phenazines and phenoxazinones from commercially available -substituted aromatic amines with very good yield (≥80%) in water. The procedure uses eosin Y (EY) as a photoredox catalyst at room temperature (RT). The highly reactive -quinone-diimine or -quinone-imine intermediate was characterized by the HR-MS technique.
本文描述了一种高效、可持续的一步法，用于从市售的取代芳香胺在水中以非常高的产率（≥80%）合成取代吩嗪和吩恶嗪酮。该方法在室温下使用曙红Y（EY）作为光氧化还原催化剂。通过高分辨质谱（HR-MS）技术对高活性的醌二亚胺或醌亚胺中间体进行了表征。
