  Synthesis of secondary amines by reductive dimerization of azides

  摘要：

  Hydrogenolysis of azides using hydrogen over 5% palladium-on-charcoal at atmospheric pressure has provided a method for the preparation of symmetrical secondary amines by a reductive dimerization process. In this process, the azide carbons of two azides become attached to an amino nitrogen with concurrent expulsion of five nitrogen atoms. (C) 1998 Elsevier Science Ltd. All rights reserved.
