Unprecedented Pd–Ag/Cu–Ag nanocluster-catalyst switch leads to a phenazine/azoarene twist for non-radical mode C–H activation vs. radical mode N–N self-coupling of anilines.

Valuable aromatic nitrogen compounds can be synthesized by reduction of nitroarenes. Herein, we report electrochemicalreduction of nitroarenes by a protocol that uses inert graphite felt as electrodes and ammonia as a reductant. Depending on the cell voltage and the solvent, the protocol can be used to obtain aromatic azoxy, azo, and hydrazo compounds, as well as aniline derivatives with high chemoselectivities

borohydride (NaBH4) in aqueous solution under ambient conditions, which can selectively produce five categories of nitrogen-containing compounds: anilines, N-aryl hydroxylamines, azoxy-, azo- and hydrazo-compounds. The catalyst is in situ-generated ultrasmall palladium nanoclusters (Pd NCs, diameter of 1.3 ± 0.3 nm) from the reduction of Pd(OAc)2 by NaBH4. These highlyactivePd NCs are stabilized by

Fe(III) complexes, [Fe(CH3CN)6][X]3 and [Fe(CH3CH2CN)6][X]3 (where X: counter anion = BC6H3(m-CF3)2}4)− and B(C6F5)−4) have been synthesized by the reaction of FeCl3 with Ag[B(X)4]. Full characterization for the complexes has been done in solution and in the solid state. The complexes are obtained in good yields and are moderately sensitive to air. All complexes have been used as catalysts for aniline

A novel synthetic strategy for phenazine formation is reported following self coupling of anilines by Pd-Ag binary nanocluster-catalysed synchronous double C-N bondformation via non-radical mode of ortho-aryl C-Hactivation.
