Depending on the N-substituents, o-phenylenediamines react in the system Cu(I) halide/amine/O2, through radicals or nitrene intermediates, to give (a) cis-cis-muconitriles (through o-dinitrenes); (b) with insertion of nitrenes into the C-H bond; or (c) with coupling of the nitrenes to diazo compounds.
