Kinetic Study on Solvolysis of 2-Methylfuran-3-carbonyl Chloride in Binary Solvent Mixtures
Rate constants for solvolysis of 2-methylfuran-3-carbonyl chloride (1) in ethanol, methanol, and aqueous binary mixtures incorporating ethanol, methanol, acetone, 2,2,2-trifluoroethanol, and 1,1,1,3,3,3-hexafluoro-2-propanol are reported. The 34 solvents give an extended Grunwald–Winstein correlation with l = 0.26 ± 0.05, m = 0.71 ± 0.04, and correlation coefficient R2 = 0.963. Activation parameters calculated from the rate constants measured at three different temperatures in five different solvents are presented. In the deuterated methanol, a solvent kinetic isotope effect of 1.15 was observed at 0°C. The kinetic features observed indicate that the reaction proceeds through an SN1 mechanism with a little SN2 character. The reactivity–selectivity principle is also followed in alcohol-water mixtures.
