• Palladium-catalysed direct heteroarylation of bromobenzenes bearing SO2R substituents at C2 or C4
  作者：Charles Beromeo Bheeter、Rongwei Jin、Jitendra K. Bera、Henri Doucet

  DOI：10.1039/c3ra40769a

  日期：——

  Palladium-catalysed direct arylation of 4- or 2-bromobenzenesulfonic acid derivatives in the presence of a variety of heteroaromatics was found to proceed using 0.1–0.5 mol% palladium acetate as the catalyst. However, both the nature and position of the SO2R substituent on such bromobenzenes has an influence on the reaction rates and yields. The presence of SO2Et or SO2NEt2 at the C2 or C4 position of bromobenzene is tolerated. Good results were also obtained from bromobenzene substituted at C4 by SO2NHPh or SO2OPh. On the other hand, the reactions of bromobenzenes bearing either SO2N(Me)CH2Ph or SO2OAr at C2 led in some cases to intramolecular reactions instead of the desired intermolecular couplings. Some reactions were performed in cyclopentyl methyl ether, which can be considered as a green solvent.

  使用0.1-0.5%摩尔的醋酸钯作为催化剂，在多种杂芳环存在下，发现钯催化的4-或2-溴苯磺酸衍生物的直接芳基化反应可以进行。然而，溴苯上SO2R取代基的性质和位置对反应速率和产率有影响。在溴苯的C2或C4位置存在SO2Et或SO2NEt2是可以容忍的。在C4位置由SO2NHPh或SO2OPh取代的溴苯也得到了良好的结果。另一方面，在C2位置带有SO2N(Me)CH2Ph或SO2OAr的溴苯的反应在某些情况下会导致分子内反应，而不是所期望的分子间偶联。一些反应在环戊基甲基醚中进行，这种溶剂可以被认为是一种环保溶剂。

  transformation successfully extends its application for the synthesis of phenanthridines and dibenzooxazepines. This new synthetic protocol not only extends the application platform for palladium-catalyzed CC coupling of aryl halides with isocyanides, but also opens atom-economic and step-economic synthetic routes for nitrogen-containing heterocyclic compounds with wide functional group compatibility.

  C(sp3)–C(sp2) cross coupling reaction between inert γ-C(sp3)–H bonds in aliphatic amines and cyanoarenes under electrochemical conditions in flow. The developed methodology takes advantage of a removable redox active auxiliary, which triggers selective 1,7-hydrogen atom transfer to functionalise an aliphatic C–H bond at the γ-position of an alkyl amine. In this reaction, a cyanoarene radical anion functions as
