โœฆ Synopsis

Ago values for the isodesmic equilibrium between substituted acetophenone enols and the corresponding methyl enol ethers are calculated from previously reported data on equilibrium constants for keto-enol tautomerism and for enol ether formation from ketones. These values agree with those expected from literature data on analogous alcohol--ether isodesmic systems.

The kinetics of the hydronium-ion catalysed hydrolysis of the following heterocyclic methyl enol ethers have been measured: 3-methoxybenzofuran, 3+ethoxybenzothiophene, 3-methoxyindole, 3-methoxy-1-methylindole, 3-methoxyfuran, 3-methoxythiophene. -. and 2-methoxythiophene. On the basis of the solv
