Versatile nickel catalysts enabled the step-economical synthesis of decorated indoles through alkyne annulations with anilines bearing removable directing groups. The CâH/NâH activation strategy efficiently occurred in the absence of any metal oxidants and with excellent selectivities.
The C−H thiolation of aniline derivatives was accomplished with a versatile nickel(II) catalyst under ligand‐free conditions. The robust nature of the nickel catalysis system was reflected by the C−H thiolation with a good functional group tolerance and an ample scope, employing anilines possessing removable directing groups. The widely applicable nickel catalyst also allowed for aniline C−H selenylations
anilines is herein reported. The reaction tolerates a broad range of aniline derivatives and provides a convenient approach for accessing the corresponding para/meta-selective difluoroalkylated products. Mechanism studies demonstrated that the initial CAr–H and N–H cycloruthenation is the pivotal step in achieving remote C–H difluoroacetylation.
