Employing sulfonyl azide as a nitrogen donor, a visible-light-enabled aerobic dealkylative imidation of tertiary and secondary amines involving C(sp3)-C(sp3) bond cleavage with moderate to excellent yields at room temperature is described. It has been demonstrated that this imidation could take place spontaneously upon visible-light irradiation, and could be facilitated considerably by a ruthenium photocatalyst and oxygen. An alternative mechanism to the previous aerobic photoredox pathway has also been proposed.

Reported herein is a straightforward protocol for approachingN-sulphonylamidinesviaan electricity-driven, iodine-mediated cross dehydrogenative condensation (CDC) between sulphonamides and tertiary amines, which features exclusive N-CH3selectivity for the amine partners. Mechanistic studies indicate that anin situgeneratedN-iodoaminium species serves as the key intermediate.

Visible-light-induced cross-coupling of arylsulfonyl azides with tertiaryamines in the presence of Eosin Y at room temperature has been achieved. This transformation features alkyl C-C bond cleavage and provides a green approach to N-sulfonylamidines under mild conditions.
