A novel and efficient photoinduced synthesis of C6-polyfunctionalized phenanthridines from three-component reactions of isocyanides, alkynes and sulfinicacids was developed. The reactions generated the corresponding products with high selectivity through the photochemical activity of the formed electron donor–acceptor (EDA) complex during the reaction via a radical tandem process under mild conditions

A novel and efficient method for selective synthesis of diaryl sulfoxides and m-arylthio sulfones has been achieved from readily available arylsulfinic acids and arenes via an unusual sulfinyl cation, providing a range of structurally diverse products in good to excellent yields under mild conditions. Notably, mechanistic investigations suggested m-arylthio sulfones were generated from diaryl sulfoxides

An efficient Ag‐promoted reaction of N‐propargyl indoles and arylsulfinic acids to 2‐sulfonated‐9H‐pyrrolo[1,2‐a]indoles was developed. The reaction underwent smoothly to give the desired products in good yields and excellent regioselectivity with broad substrate scope using arylsulfinic acids as stable and less toxicity sulfonylating agent.
