Cyclohexane and Benzene Amination by Catalytic Nitrene Insertion into C−H Bonds with the Copper-Homoscorpionate Catalyst Tp Br3 Cu(NCMe)

The complex TpBr3Cu(NCMe) catalyzes, at room temperature, the insertion of a nitrene group from PhINTs into the carbon-hydrogen bond of cyclohexane and benzene, as well as into the primary C-H bonds of the methyl groups of toluene and mesitylene, in moderate to high yield.
