  摘要：

  摘要 在有机分子的同一碳中心加入两个不同的硼烷基，由于其通过逐步双碳硼键转化促进可控、精确合成的潜力，引起了越来越多的研究兴趣。在此，我们报告了一种通过现成的炔烃与中性 sp2-sp3 二硼试剂 (NHC)BH2-Bpin (NHC=N-heterocyclic carbene) 反应，立体选择性地获得非对称 1,1 二硼烯 (UDBA) 的方法。由于 sp2 和 sp3 硼烷基的化学性质很容易区分，因此可以对生成的 UDBA 进行可控的逐步衍生。通过这一过程，可制备出各种多功能烯烃和有机硼，如酰基硼烷，而这些烯烃和有机硼是很难用其他方法制备的。

  been shown to favor aryl thiolate reductive elimination at elevated temperatures and in some cases at room temperature, compared with the analogous diarylamido/bis(phosphine) (PNP)Rh pincer system. Concerted reductive elimination has been studied with 6a directly and in the presence of aryl bromide and aryl chloride traps. This investigation demonstrates a clear rate dependence on aryl chloride concentration

• Amide synthesis <i>via</i> nickel-catalysed reductive aminocarbonylation of aryl halides with nitroarenes
  作者：Chi Wai Cheung、Marten Leendert Ploeger、Xile Hu

  DOI：10.1039/c7sc03950f

  日期：——

  Aminocarbonylation of aryl halides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the development of nickel catalysis for the first three-component reactions of aryl halides, Co2(CO)8, and nitroarenes under reductive conditions to produce aryl amides. A

  芳基卤化物的氨基羰基化是酰胺合成中最有用的方法之一，但是硝基芳烃虽然比苯胺更经济，更易获得，但在该方法中并未用作氮源。此处报道的是在还原条件下，芳基卤化物，Co 2（CO）8和硝基芳烃在头三组分反应中生成镍酰胺的镍催化的进展。广泛的（杂）芳基碘化物和溴化物以及硝基（杂）芳烃是合适的反应伙伴，并且已经实现了高官能团相容性。该方法可用于芳基酰胺的流线型合成。
