Solvent-free synthesis of 14-Aryl-14 H-dibenzo[ a, j]xanthenes catalyzed by recyclable and reusable iron(III) triflate.

A solvent-free and efficient synthesis of 14-aryl-14 H-dibenzo[ a, j]xanthenes through the one-pot condensation of β-naphthol and aldehydes catalyzed by recyclable and reusable Iron(III) triflate was reported. Notably, the presented method features short reaction time, excellent yield, and simple experimental procedure. [ABSTRACT FROM AUTHOR]
