• An Efficient Silane-Promoted Nickel-Catalyzed Amination of Aryl and Heteroaryl Chlorides
  作者：Georg Manolikakes、Andrei Gavryushin、Paul Knochel

  DOI：10.1021/jo702219f

  日期：2008.2.1

  A new silane-promoted nickel-catalyzed amination of aryl chlorides with 0.5 mol % of Ni(acac)2, 1 mol% of 3,5,6,8-tetrabromo-1, 10-phenanthroline, and polymethythydrosiloxane was developed. A broad range of aryl and heteroaryl chlorides can be coupled with secondary amines and anilines to give the desired (het)arylamines in good to excellent yields. The reaction is sensitive to the nature and amount of the silane promoter.

  日期：2000.4

  The 2,2'-bipyridine liganded Ni catalyst has revealed a good selectivity in the mono arylation of piperazine starting from aryl chlorides allowing a selective and efficient synthesis of N-arylpiperazines using stoichiometric amounts of reagents. The preparation of N,N'-diaryl substituted piperazines is also described. (C) 2000 Elsevier Science Ltd. All rights reserved.

  日期：1998.2

  A Pd/P(t-Bu)(3) catalyst system has revealed very high activity and selectivity for the amination of N-(hetero)aryl halides with unprotected piperazine. A wide variety of N-(hetero)arylpiperazines could be prepared using this catalyst. Turnover numbers up to 6400mol/mol have been obtained. (C) 1998 Elsevier Science Ltd. All rights reserved.
