Rh2(II)-Carboxylate complexes are established N-atom transfer catalysts that trigger the formation of N-heterocycles from 2-substituted aryl azides.  Experimental data suggests that N-heterocycle formation is dependent on the identity of the ortho-substituent and occurs through either a stepwise C�H bond amination or 5-electron-4-p-electrocyclization mechanism.  Substrates that can react through either pathway were investigated, and the properties that lead to bifurcation of the mechanism were identified and will be discussed.
