Substituted di-1-azulenyl ketones composed of 3,8-dimethyl-5-isopropyl-1-azulenyl and/or 4,6,8-trimethyl-1-azulenyl group were refluxed in ethanol in the presence of p-toluenesulfonic acid to give substituted azulenes and ethyl azulene-1-carboxylates derived from the cleavage of either of C-CO bonds of di-1-azulenyl ketones.The facility and the product distributions of the ethanolysis were affected markedly by the substitutents.
