A tin(II) complex coordinated by a sterically demanding -phenylenediamido ligand is synthesized. The ligand is redox-active to reach a tin(II) complex with the diiminobenzosemiquinone radial anion in the oxidation by AgPF. The tin(II) complex reacts with a series of nosylazides (-NOCH-SO-N; = , , or ) at -30 °C to yield the corresponding nitrene radical bound tin(II) complexes. The nitrene radical complexes exhibit C(sp)-H activation and amination reactivity.
