The Effect of Both ?-Donor Substituents and Acid Media on the Formation of Trityl Cations, Studied by Relaxation Methods and NMR-Spectroscopy

Trityl trifluoroacetates were taken to study why ion formation from ionogens is favoured by acid media.From relaxation measurements, NMR-spectroscopy and conductivity studies it was found that this effect is due to anion solvation by acid, namely a specific solvation of the free anions and a statistical solvation of the anions bound in the ionogen.This leads to a drastically reduced ion recombination rate constant even at low concentrations of acid and an increased dissociation rate constant at rather high concentrations of acid. -.Keywords: Kinetics/ Ion solvation/ Carbenium ions/ NMR-spectroscopy
