  Palladium-catalyzed monoamination of dihalogenated benzenes

  摘要：

  The palladium-catalyzed monoamination of symmetric dibromobenzenes can be performed using a catalyst based on Pd(2)dba(3) and BINAP in the presence of NaO(t-Bu). The analogous transformation of non-symmetric bromoiodobenzenes is most effectively performed with Xantphos as the ligand, while reactions with BINAP were non-selective. These transformations can be scaled uneventfully to >10 g quantities. They do not require drybox or Schlenk techniques, and all reagents are weighed out in air. The resulting monobromoanilines are versatile intermediates for further synthetic transformations. (C) 2008 Elsevier Ltd. All rights reserved.
