ABSTRACT The present work documents organophotocatalytic transformation of N‐phosphorylated arylhydrazones into indazoles. The strategy relies on the visible light‐mediated generation of N‐centered radical intermediate. The reaction employs organic dye as a photocatalyst and air as a terminal oxidant. The mild conditions, operational simplicity and fairly general scope are the notable attributes of the methodology.
