We report an electrophotocatalytic process that enables the thiocyanation and sulfonylation/cyclization of alkenes. It is applicable to a wide range unactivated alkenes, using inexpensive photocatalyst 2,4,6-triphenylpyrylium tetrafluoroborate (TPPT) produce diverse array heterocycles containing sulfonyl thiocyano groups with good functional group tolerance. The protocol operates under mild, chemical oxidant- transition-metal-free, broad scope substrates. Preliminary mechanistic studies suggest reaction involves combination electrolysis reductive quenching photocatalytic cycle TPPT.
