The electronic structure of the nitrogen atoms of allyl (5-pyridin-2-yl-[1,3,4]-thiadiazol-2-yl)-amine
The resonance structures of allyl-(5-pyridin-2-yl-[1,3,4]-thiadiazol-2-yl)-amine have been determined by means of its H-1- (100 MHz, 500 MHz) C-13- and N-15-NMR spectra and B3LYP/6-31G* computations. The tautomeric equilibrium of this compound has been observed in the H-1-NMR spectra ( 100 MHz).
