A photoredox-catalyzed three-component reaction of aryldiazonium tetrafluoroborates with sodium metabisulfite and 2,2-difluoro enol silyl ethers is described. By using as the source sulfur dioxide, this method provides an elegant access to α,α-difluoro-β-ketosulfones in moderate good yields under mild conditions, features a broad substrate scope wide functional group tolerance. Both difluoromethyl sulfone moiety can be introduced single step. Based on experimental results, single-electron transfer pathway proposed insertion dioxide.

Efficient C4-arylation and domino C4-arylation/3,2-carbonyl migration of indoles have been developed. The former route enables in a highly efficient mild manner the latter provides an alternative straightforward protocol for synthesis C2/C4 disubstituted indoles. mechanism studies imply that different reaction pathways were tuned by distinct acid additives, which led to either Pd(i)-Pd(ii) pathway or Pd(ii) catalysis.
