Brief Communications


  1. 1.

    In the catalytic hydrogenation of succinonitrile, the main product was the cyclic secondary amine, pyrrolidine.

  2. 2.

    In the hydrogenation of isophthalonitrile the product was m-xylene-α,α′-diamine, and in the hydrogenation of phthalonitrile, the sole product was isoindoline.

  3. 3.

    The question of reaction conditions and reaction mechanism in the formation of nitrogenous heterocycles in the catalytic reduction of dinitriles was discussed.
