Late-stage functionalization (LSF) introduces functional group or structural modification at
the final stage of the synthesis of natural products, drugs, and complex compounds. It is …

Organothianthrenium salts are a class of compounds containing a positively charged sulfur
atom and a neutral sulfur atom. Over the past years, organothianthrenium salts have been …

Selective cleavage and functionalization of C–C bonds in alcohols is gaining increasing
interest in organic synthesis and biomass conversion. In particular, the development of …

Conspectus C–C single bonds are ubiquitous in organic compounds. The activation and
