Recent Advances to Mediate Reductive Processes of Nitroarenes Using Single-Electron Transfer, Organomagnesium, or Organozinc Reagents

Abstract

Nitroarenes are readily available compounds that are commonly utilized in reductive processes to form C–NAr bonds via reactive nitrogen intermediates. Recent advances in the development of reductive reactions of nitroarenes using organomagnesium, organozinc, and single-electron transfer reagents are discussed within this short review.
