Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The equilibrium positions of 4-carbomethoxy-3-thiophanone (I), 2-carbomethoxy-4-methyl-3-thiophanone (II), 4,5-dicarbomethoxy-3-thiophanone (III), and 4-carbethoxy-5-phenyl-3-thiophanone (IV) in acetonitrile, dioxane, and alcohols was determined. The Meyer equation is satisfied for ketones I and II paired with acetylacetone and for III and IV paired with methyl cyclopentanone-2-carboxylate in alcohol solutions.
