An efficient photoinduced strategy for the hydrogenation and arylsulfonylation of alkenes has been developed. The reaction afforded a range of hydrogenated products and sulfonated oxindoles in high yields under external photocatalyst-free, oxidant- and reductant-free conditions. Mechanistic investigations suggested this transformation is driven by the photochemical activity of hydrogen bond donor-acceptor complex, generated from the substrates of arylsulfinic acids and C6-(vinyl sulfone)phenanthridines or N-arylacrylamides via hydrogen bond interaction.

A catalytic system consisting of KI, 18-crown-6, and TBHP for arylsulfonylation of activated alkenes with sulfonylhydrazides as sulfonyl precursor is described. This protocol provides a practical and environmentally benign method for the construction of sulfonated oxindoles in water.
