title: Catalytic insertion of diazo compounds into N-H bonds: the copper alternative.
abstract: The complexes TpxCu (Tpx = homoscorpionate) catalyse the insertion of diazo compounds into nitrogen-hydrogen bonds of amines and amides, under very mild conditions, with quantitative yields being obtained with equimolar ratios of reactants.
