Abstract
The radical and ionic structures of (3-phenyl-allyl-) (5-pyridin-2-yl-[1,3,4] thiadiazol-2-yl)-amine 2A(I) ⇔ 2A(I)' ⇔ 2A(I)' a , 2A(II) ⇔ 2A(II)' ⇔ 2A(II)' a have been determined by means of its 1 H (100 MHz, 500 MHz) 13 C and 15 N NMR spectra and B3LYP/6-31G** computations. The tautomeric equilibrium of 2A(I)' ⇒ 2B', 2A(II)' => 2C(II)' has been observed in the 'H NMR spectra (100 MHz).
