REVERSIBLE CARBON PROTONATION IN THE HYDROLYSIS OF HETEROCYCLIC ENOL METHYL ETHERS

The kinetics of the hydronium-ion catalysed hydrolysis of the following heterocyclic methyl enol ethers have been measured: 3-methoxybenzofuran, 3-methoxybenzothiophene, 3-methoxyindole, 3-methoxy-1-methylindole, 3-methoxyfuran, 3-methoxythiophene, and 2-methoxythiophene.On the basis of the solvent isotope effect kH/kD = 3.08 and the failure to detect deuterium exchange when the solvent was CD3CN:D2O (9:1 v/v) it was concluded that the rate limiting step in the hydrolysis of 3-methoxybenzofuran is C-protonation.The effect of the ring-oxygen atom was measured by comparing the rate of hydrolysis of 3-methoxybenzofuran with that of 3-methoxyindene which occurs 2100 times faster.In contrast to the behaviour of 3-methoxybenzofuran the isotope effects, kH/kD, for the hydrolyses of 3-methoxyfuran, 3-methoxythiophene, 3-methoxyindole, 3-methoxy-1-methylindole and 2-methoxythiophene are ca 0.4 – 0.5 and deuterium exchange is much faster than hydrolysis when the solvent is CD3CN:D2O (9:1 v/v).It was therefore concluded that with these compound C-protonation is rapid and reversible and that slow step is attack by water on the intermediate cation.

Does aromaticity in a reaction product increase or decrease the intrinsic barrier? Kinetics of the reversible deprotonation of benzofuran-3(2H)-one and benzothiophene-3(2H)-one

A kinetic study of the reversible deprotonation of benzofuran-3(2H)-one (3H-O) and benzothiophene-3(2H)-one (3H-S) by amines and hydroxide ion in water at 25 C is reported. The respective conjugate bases, 3–O and 3–S, represent benzofuran and benzothiophene derivatives, respectively, and thus are aromatic. The main question addressed in this paper is whether this aromaticity has the effect of enhancing or lowering intrinsic barriers to proton transfer. These intrinsic barriers were either determined from Bronsted plots for the reactions with amines or calculated on the basis of the Marcus equation for the reaction with OH-; they were found to be lower for the more highly aromatic benzothiophene derivative, indicating that aromaticity lowers the intrinsic barrier. It is shown that the reduction in the intrinsic barrier is not an artifact of other factors such as inductive, steric, resonance, polarizability, and pi-donor effects, although these factors affect the intrinsic barriers in a major way. Our results imply that aromatic stabilization of the transition state is ahead of proton transfer; this contrasts with simple resonance effects, which typically lag behind proton transfer at the transition state, thereby increasing intrinsic barriers.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H6OS, you can also check out more blogs about130-03-0
