• Scope and Limitations of the Pd/BINAP-Catalyzed Amination of Aryl Bromides
  作者：John P. Wolfe、Stephen L. Buchwald

  日期：2000.2.1

  Mixtures of Pd(2)(dba)(3) or Pd(OAc)(2) and BINAP catalyze the cross-coupling of amines with a variety of aryl bromides. Primary amines are arylated in high yield, and certain classes of secondary amines are also effectively transformed. The process tolerates the presence of several functional groups including methyl and ethyl esters, enolizable ketones, and nitro groups provided that cesium carbonate is

  Pd（2）（dba）（3）或Pd（OAc）（2）与BINAP的混合物催化胺与各种芳基溴化物的交叉偶联。伯胺以高收率芳基化，某些类型的仲胺也可以有效转化。如果使用碳酸铯作为碱，该方法可耐受几种官能团的存在，包括甲基和乙基酯，可烯醇化的酮和硝基。大多数反应在0.5-1.0 mol％的钯催化剂下完成。在某些情况下，可以使用低至0.05mol％Pd的催化剂水平。如果将Pd（OAc）（2）用作预催化剂，则反应会更快，并且将试剂添加到反应中的顺序对反应速率有很大影响。催化过程可能通过双（膦）钯配合物作为中间体进行。与相应的单齿三芳基膦的配合物相比，这些配合物不易发生不希望的副反应，从而导致收率降低或催化剂失活。

  Reaction conditions for the three‐component synthesis of aryl 1,3‐diketones are reported applying the palladium‐catalyzed carbonylative α‐arylation of ketones with aryl bromides. The optimal conditions were found by using a catalytic system derived from [Pd(dba)2] (dba=dibenzylideneacetone) as the palladium source and 1,3‐bis(diphenylphosphino)propane (DPPP) as the bidentate ligand. These transformations

  据报道，使用钯催化的酮与芳基溴化物的羰基化α-芳基化反应，可以合成芳基1,3-二酮的三组分反应条件。通过使用衍生自[Pd（dba）2 ]（dba =二亚苄基丙酮）作为钯源和1,3-双（二苯基膦基）丙烷（DPPP）作为二齿配体的催化体系找到了最佳条件。这些转化是在两室反应器COware中进行的，仅应用了从CO释放化合物9-甲基芴-9-羰基氯（COgen）产生的1.5当量的一氧化碳。该方法论证明可适用于多种芳基和杂芳基溴化物，从而导致多种芳基1,3-二酮。依靠31 P和进行13 C NMR光谱分析以确定可能的催化途径。我们的结果表明，[Pd（dba）2 ]和DPPP的组合仅在存在苯乙酮烯醇钠的情况下才对4-溴苯甲醚具有反应性，这表明[Pd（dppp）（enolate）]阴离子是在生成苯丙酮之前最初生成的。氧化加成步骤。随后将CO插入[Pd（Ar）（dppp）（烯酸酯）]物种中，提供了1,3-二
