Reductive N‑Alkylation of Nitro Compounds to <i>N</i>‑Alkyl and <i>N</i>,<i>N</i>‑Dialkyl Amines with Glycerol as the Hydrogen Source

Abstract

As the sustainable and promising hydrogen source, here, glycerol was directly used as the hydrogen source for the reductive amination of alcohol using nitrobenzene as the starting material. The amination of alcohols, especially aliphatic alcohols with different structures, was realized, and mono- or disubstituted amines were synthesized with excellent yields. The reaction mechanism was also explored
