Implication

Demonstrates a novel organophotoredox catalyst for efficient coupling reactions with aryl halides, implying potential for advanced synthetic applications.

Abstract

Phenoxazine-based organophotoredox catalyst PC-A was prepared using a two-step process starting from 2-(3,5-di-tert-butyl-2hydroxyphenylamino)benzonitrile, with a catalytic amount of MnCl2•4H2O, and finally by substituting the NH proton of the phenoxazine moiety...
