  • Title: Cobalt Nanoparticles Catalyzed N-Heterocycles Synthesis via Acceptorless Dehydrogenative Coupling.
    Author: Ren C, Chen S, Yuan Z, Fu R, Cui Y, Ma Z, Li W, Li X.
    Journal: Chemistry; 2024 Oct 08; 30(56):e202402168. PubMed ID: 39072825.
    Abstract:
    The acceptorless dehydrogenation reaction is a sustainable and atom-economical methodology in organic synthesis, resulting in the byproducts of only hydrogen or water. Herein, a robust Co-Si/CN catalyst (derived from ZIF@SiO2 composite) has been synthesized through a one-step assembly process via pyrolysis and etching. This catalyst has been employed for the acceptorless dehydrogenative coupling of 2-aminoalcohols with secondary alcohols, enabling efficient conversion of various substrates into desired quinoline or pyridine derivatives with a yield of up to 94 %.
