A Quantitative Analysis of Solvent Effects on Keto-Enol Tautomeric Equilibria
Abstract
dc:descriptionSolvent dependent tautomeric equilibria of dimedone, 2-methyl-1,3-cyclohexanedione, anthrone, acetylacetone, ethyl acetoacetate and 3-oxabicyclo{4.3.0}-2,9-dioxononane, representative of the major classes of (beta)-dicarbonyl and phenolic tautomeric equilibria, are determined in a variety of solvents by high dilution FT NMR and UV studies. O-Methylated enol ethers are used as models for the ultraviolet chromophores of dimedone and 2-methyl-1,3-cyclohexanedione, and a comparison is made to NMR results on these systems. Temperature studies are performed to examine trends in (DELTA)H('0) and (DELTA)S('0) in the different systems.
