Chelation sites of the proton and structures of chelated six-atom ring systems have been determined for 2-arylhydrazono-3-aryliminopropane-1-ones and 2-arylhydrazono-1,3-bis(arylimino)propanes. Nuclear magneticresonancespectroscopy allowed determination in these compounds of two types of exchange of the chelated proton. The first type concerns an intramolecular exchange between the two nitrogen atoms
