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. (Figure presented.).

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. Let there be light!
