A copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with sulfonylhydrazides through a tandem radical process was developed. This methodology provided an alternative strategy for the synthesis of sulfonated oxindoles by forming C–S, C–N and C–C bonds in a single operation.

A novel photocatalytic synthesis of sulfonated oxindoles from N‐arylacrylamides and arylsulfinic acids was developed by means of a cascade C−S/C−C bond‐formation process. This method provides mild, efficient, and atom‐economical access to various sulfonated oxindoles in water.
