Light-promoted, nickel-catalyzed C–N coupling of (hetero)aryl halides with benzophenone hydrazone for the synthesis of nitrogen-containing heterocycles

A highly effective method for synthesizing N -arylhydrazones by means of light-promoted C–N coupling of (hetero)aryl halides with benzophenone hydrazone with catalysis by a Ni( ii )–aryl halide complex was reported.
