benzylic sp3 C−H amination is disclosed using aryl nitro compounds as aryl nitrene precursors. Organosilicon reagent N,N’-bis(trimethylsilyl)-4,4’-bipyridinylidene (Si-DHBP) served as an efficient reductant in the transformation, enabling the in situ generation of aryl nitrene species for the synthesis of 2-arylindolines from the corresponding nitroarene compounds.

A dinuclear Co(ii) complex supported by a modular, tunable redox-active ligand system is capable of selective C–H amination to form indolines from aryl azides in good yields at low (1 mol%) catalyst loading.
