A rhodium(ii)/rhodium(iii) redox couple for C–H bond amination with alkylazides: a rhodium(iii)–nitrenoid intermediate with a tetradentate [14]-macrocyclic ligand

The catalytic activity of a rhodium( ii ) dimer complex, [Rh II (TMAA)] 2 (TMAA = tetramethyltetraaza[14]annulene), in C–H amination reactions with organic azides is explored.
