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