Visible Light‐Mediated Reactions of β‐Nitroalkenes

Organic transformations using visible light‐mediated photoredox reactions received significant attention in the past several years. Recently, nitroalkenes have emerged as an excellent coupling partner in the visible light‐mediated photoredox reactions. Due to the easy availability and diverse reactivity, several methodologies are reported on the photoredox‐mediated reactions of nitroalkenes to attain different types of alkenes and heterocycles. Variety of reactions including denitrative coupling reactions, addition reactions and cycloadditions, etc. are reported. However, a review that focuses entirely on this topic has not appeared yet. Considering the synthetic potential of these class of reactions, we provide a summary of various methodologies developed for the reactions of nitroalkenes under visible light photoredox catalysis.
