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.
