N-Aminopyridinium Ylide-Directed, Copper-Promoted Chalcogenation of Arene C-H Bonds.

Published in: The Journal of organic chemistry (2020)

N-Aminopyridinium ylide-directing group is employed for copper-promoted chalcogenation of sp2 C-H bonds with aryl and alkyl disulfides as well as diphenyl diselenide. Reactions proceed in hexafluoroisopropanol (HFIP) solvent at elevated temperatures and are promoted by copper(II) acetate.
