  Threefold and chemoselective couplings of triarylbismuths with benzylic chlorides and iodides using palladium catalysis

  摘要：

  本文描述了对三芳基铋试剂与苄基氯和碘进行三重偶联的钯催化研究。经过优化的实验条件操作简单，使得多种三芳基铋与苄基氯和碘的三重偶联得以实现。这两种优化的实验方案使得不对称二芳基甲烷的合成变得高效。在本研究的过程中，还实现了苄基氯和碘的化学选择性转化。

  日期：2012.8

  alkyl 2-benzylacrylates and 2-benzylacrylonitriles were synthesized by means of atom-economic cross-couplings of Baylis–Hillman bromides or acetates with BiAr3 under palladium-catalyzed conditions. These reactions, involving threefold aryl couplings using BiAr3 reagents with bromides and acetates, are fast and are completed in 1–2 h with high product yields.

  Cross-coupling studies using bromopyridines and bromoquinolines with triarylbismuths as threefold coupling reagents in substoichiometric amounts under Pd-catalysed conditions are disclosed. The reactivity was high with both mono- and dibromopyridyl substrates, and mono- and bis-couplings were carried out regioselectively. A library of monoaryl and diaryl pyridines was formed in high yields. A one-pot
