Direct Coupling of Naphthalene and Sulfonimides Promoted by DDQ and Blue Light
Aromatic C–H amination chemistry has attracted significant attentions as an alternative of conventional amination of aryl halides. Among C–H amination reactions, dehydrogenative coupling of arenes and N–H reagents represents an ideal transformation because prefunctionalization steps of arenes or aminating reagents are not required. Herein, we report direct C–H/N–H coupling between naphthalene and sulfonimides mediated by 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) as a photosensitizer under irradiation of blue light.
