The tautomeric behaviour of individual compounds is therefore strongly affected by the nature of the substituent, as assessed via NMR spectroscopy in terms of tautomerisation constants K-T = C-Z2/C-N2 (where C-Z2 and C-N2 are equilibrium concentrations of Z2 and N2 forms in a given solvent). Individual tautomers were characterised by B-11 and H-1 NMR spectroscopy and the structure of the monomethylated N2b tautomer was determined by an X-ray diffraction study.
