Spanish abstract Se describe una metodología simple para la síntesis de 5Hdibenzo[b,i]xanteno-tetraonas y aril-14H-dibenzo[a,j]xantenos. Los xantenos son obtenidos por condensación de aldehídos con 2-naftol o 2-hidroxi-1,4-naftoquinona en presencia de cloruro férrico hexahidratado. Las reacciones se llevan a cabo en ausencia de disolvente, son limpias, de bajo costo y con alto rendimiento
English abstract A simple and convenient procedure for the synthesis of 5Hdibenzo[b,i]xanthene-tetraones and aryl-14H-dibenzo[a,j]xanthenes is described through the condensation of aldehydes with 2-naphthol or 2-hydroxy-1, 4-naphthoquinone under solvent-free conditions in the presence of ferric chloride hexahydrate. This method has the advantages of high yields, cleaner reaction, simple work-up and cost efficiency
