The effect of structural factors on the position of the enol-enethiol equilibrium, the thermodynamic parameters, and the interconversion rate of the tautomers was investgated in the series of polyfluorinated monothio 1,3-ketones (RFCOCH2CSR, where RF = CF3, H(CF2)2; R = Alk, Ph) by PMR spectroscopy.At temperatures below -70 deg C the individual PMR spectra of these forms were recorded in a number of cases.It was established that increase in the size of the substituent R shifts the equilibrium substantially toward the enolic form but has little effect on the interconversion rate of the tautomers.
