Sulfur Mediated Allylic C-H Arylation, Epoxidation and Aziridination

Transition-metal-free, sulfur mediated allylic C-H arylation, epoxidation and aziridination were realized through one-pot procedures. The reaction design involved initial addition between olefins and triflic anhydride activated sulfoxides, followed by subsequent reactions of the allylic sulfur ylides generated under basic conditions with arylboronic acids, aldehydes, or aldimines, to give allylic arylation, epoxidation or aziridination products, respectively.
