Spectrometric study on the triazolium ylides
Abstract
The pKa values of triazolium ylides represent a quantitative parameter for the estimation of their stability. In the case of tautomeric triazolium ylides the differences in pKa values correspond to the differences in theoretical ΔH or ΔE values. The experimental values of pKa were obtained using a spectrometric method that involves the titration of triazolium salts.
