Hydrogenative coupling of nitriles with diamines to benzimidazoles using lignin-derived Rh2P catalyst

iScience, 2021
Summary: Nitrile (C≡N bond) activation for direct organic synthesis has been less explored so far due to a high redox potential of nitrile and its low dissociation energy of C−CN bond.
