  Efficient synthesis of trifluoromethyl and difluoromethyl-substituted oxindoles was achieved by reacting Langlois reagent or Baran reagent with N-arylacrylamides. However, the reaction of aryl sulfinic acid sodium salts with N-arylacrylamides did not give the desulfinative products, instead, aryl sulfonated products were produced.

  通过 Langlois 试剂或 Baran 试剂与 N-芳基丙烯酰胺反应，实现了三氟甲基和二氟甲基取代的羟吲哚的有效合成。然而，芳基亚磺酸钠盐与N-芳基丙烯酰胺的反应没有得到脱亚磺化产物，而是产生了芳基磺化产物。

  A metal-free and cost-effective synthesis protocol has been initially proposed for the construction of CF3-containing oxindoles via the direct oxidative trifluoromethylation of activated alkenes with Langlois’ reagent (CF3SO2Na). The present methodology, which utilizes very cheap CF3 reagent and a simple oxidant, provides a convenient and practical approach to CF3-containing oxindoles with a wide variety

  日期：2015.6

  With this method, a series of CF3-containing aza-heterocycles with high selectivity were fabricated in moderate to good yields. Preliminary mechanistic studies revealed that the exceptional transformation was originated from the synergistic effect of photogenerated electrons and holes. Density function theory (DFT) was adopted to understand the high selectivity of this photocatalytic chemical transformation
