G. Surpateanu et al., CHARACTERIZATION OF THE TAUTOMETRIC EQUILIBRIUM OF TRIAZOLIUM YLIDS BY NMR-SPECTROSCOPY, Journal de chimie physique et de physico-chimie biologique, 91(10), 1994, pp. 1648-1657
The monitoring by H-1 NMR of the kinetics of the tautomeric equilibriu
m between the triazolium ylids 1f-h and 2f-h confirms the existence of
a dynamic equilibrium and corroborates the results obtained by the ch
emically induced perturbation of the equilibrium.
