Recent applications of phenyl hydrazine in photoinduced chemical transformations

Phenyl hydrazine has attracted attention in photoredox catalytic synthetic strategies for the formation of carbon-carbon (C-C) bond and Carbon-Heteroatom (C-N, C = N, C-P, C-S, S-N) bonds, because of low cost and ease of availability make it a promising alternative method for typical transition metal complex-based photocatalyzed synthesis. In this review, we have focused on the recent radical coupling ­reactions of phenyl hydrazine via photochemical strategies to form carbon–carbon and carbon–heteroatom (N, P, S) bonds along with mechanism involved in their reaction.
