highly efficient method for nickel‐catalyzed C−N bond formation between sulfonamides and aryl electrophiles. This technology provides generic access to a broad range of N‐aryl and N‐heteroaryl sulfonamide motifs, which are widely represented in drug discovery. Initial mechanistic studies suggest an energy‐transfer mechanism wherein C−N bond reductive elimination occurs from a triplet excited NiII complex

(3) [HL3 = N-(benzothiazol-2-yl)benzenesulfonamide] complexes can best be described as having a distorted squareplanar geometry, that of the [Cu(L4)2(phen)] (4) [HL4 = N(benzothiazol-2-yl)toluenesulfonamide] complex shows a strictly square-planar geometry. The [Cu(L2)2(phen)MeOH] (2) [HL2 = N-(6-chlorobenzothiazol-2-yl)toluenesulfonamide] complex displays an axially elongated square-pyramidal coordination
