This study introduces an efficient method for synthesizing substituted phenazines and phenoxazinones in water using a photoredox catalyst, yielding over 80%. The highly reactive intermediate was characterized by HR-MS technique.
This paper describes an efficient, sustainable, one-step procedure for synthesizing substituted phenazines and phenoxazinones from commercially available ortho-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 o-quinone-diimine or o-quinone-imine intermediate was characterized by the HR-MS technique.
