Metal-Free Difluoromethylthiolation, Trifluoromethylthiolation, and Perfluoroalkylthiolation with Sodium Difluoromethane- sulfinate, Sodium Trifluoromethanesulfinate or Sodium Perfluoro- alkanesulfinate
A method for direct difluoromethylthiolation of Ar−H bonds is introduced. The stable and easy-to-handle HCF2SO2Na is reduced with (EtO)2P(O)H in the presence of TMSCl to generate HCF2S+ for the regioselective difluoromethylthiolation of aromatic compounds including indoles, pyrroles, and activated benzenes. This method is also applicable for the trifluoromethylthiolation with CF3SO2Na and the perf
介绍了一种直接的二氟甲硫基化Ar-H键的方法。在TMSCl存在下,用(EtO)2 P(O)H还原稳定易处理的HCF 2 SO 2 Na ,生成HCF 2 S +,用于芳香族化合物(包括吲哚,吡咯和活化)的区域选择性二氟甲基硫醇化反应苯。该方法也适用于用芳烃和杂芳烃用CF 3 SO 2 Na进行三氟甲基硫醇化和用R f SO 2 Na进行全氟烷基硫醇化。还讨论了与无金属亲电性氟代烷基硫基化反应相关的反应机理。

Ar-Rh(III) pivalate complexes assembled in situ from the reaction of [RhCl(coe)2]2 (coe = cis-cyclooctene), [p-(CF3)C6H4]3P, and CsOPiv effectively catalyzed the direct C-arylation of free (NH)-indoles and (NH)-pyrroles in good yields and with high regioselectivity. The reaction displayed excellent functional group compatibility and low moisture sensitivity. Kinetics studies support a mechanism involving

A synthetic approach to dihydropyrrolizine and tetrahydroindolizine scaffolds from pyrroles has been developed. The key step, a titanocene(III)‐catalyzed radical arylation that proceeds by C−H functionalization is atom‐economical and tolerates a large variety of functional groups. The reaction is therefore attractive for the swift assembly of functional and structural diversity.
