Cyclization of Aryl Acyl Radicals Generated fromS-(4-Cyano)phenyl Thiolesters by a Nickel Complex Catalyzed Electroreduction

Abstract
Aromatic acyl radicals generated from S-(4-cyano)phenyl 2-alkenylthiobenzoate by a nickel complex catalyzed electroreduction undergo 5- and 6-exo cyclization to give 1-indanone and dihydro-1-naphthalenone derivatives, respectively.
