Abstract In the course of the synthesis of new fluorophores for molecular recognition an experimental ( 1 H NMR) and theoretical (DFT) study of the ring‐chain isomerism of 3‐(pyridin‐2‐yl)[1,2,3]triazolo[1,5‐ a ]quinoline derivatives ( A ) into 2‐([1,2,3]triazolo[1,5‐ a ]pyridin‐3‐yl)quinoline derivatives ( B ) has been carried out. The rearrangement is influenced by steric and electronic effects of the substituents present on the quinoline ring. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
