  摘要：

  公开了一种用于将2-硝基-1,1'-联苯还原为相应的2-氨基-1,1'-联苯的改进且简化的基于In的方案。该方法仅利用化学计量的铟粉作为还原剂以及化学计量的氯化铵。后处理非常简单，仅需简单过滤后反应混合物，随后在减压下除去反应介质。还证明该方法可与多种官能团一起使用，以提供高至极高的目标2-氨基-1,1'-联苯目标产率。还提供了反应机制的建议。

  A simple and efficient method for Suzuki cross-coupling of highly substituted and congested 1-chloro-2-nitrobenzene with phenylboronic acid was developed, investigated, and optimized. The reaction conditions comprises a mixture of MeOH and water (4:1) as the reaction medium, readily available and cheap Pd(PPh3)4 as catalyst, sodium carbonate as base, and microwave heating, which affords a fast reaction
