An NMR observation of the N-methylideneamine–hexahydrotriazine equilibrium
Abstract
The first trimeric N-methylideneamine from a heterocyclic amine (4-aminoantipyrine, 1) has been fully characterized and its X-ray diffraction structural determination carried out; also the equilibrium between the trimer 2 and the monomer 3 has been studied by 1H and 13C NMR spectroscopy.
