Abstract

S-Arylation of nitro compounds-heterocumulene adducts with CuI as the catalyst, K2CO3 as the base, and highly efficient was successfully implemented without the help of an additional ligand under ultrasound irradiation in MeCN at room temperature. The use of simple and readily available starting materials, no need for column chromatography, mild copper-catalytic reaction conditions, good yields (70–89%), application of the sonochemical methodology, and short reaction times are remarkable specifications of this protocol.
