Abstract
BiVO4-NPs can be used as a new and efficient nano-catalyst for the promotion of the synthesis of 1,8-dioxo-octahydro xanthenes derivatives. The structures of the products were characterized by their physical properties, comparison with authentic samples and IR, 1H NMR and 13C NMR spectroscopy. Easy preparation of the catalyst, mild reaction conditions, easy work-up procedure, excellent yields and short reaction times are some of the advantages of this work.
Highlights
Xanthenes and their derivatives have received special attention due to their diverse array of biological activities such as anti-inflammatory, antibacterial and antiviral activities [1,2,3]

Summary
Xanthenes and their derivatives have received special attention due to their diverse array of biological activities such as anti-inflammatory, antibacterial and antiviral activities [1,2,3] These compounds can be used as leuco dyes [4], in laser technology [5] and pH-sensitive fluorescent materials for the visualization of biomolecular assemblies [6]. 1,8-Dioxo-octahydro xanthene derivatives are among the most important types of xanthenes and for this reason several methods are reported for the synthesis of 1,8-dioxooctahydro xanthenes using a variety of catalysts and reagents [7,8,9,10,11,12,13,14,15,16,17]. In recent years and because of the unique properties of nano-particles, synthetic chemists focused on the synthesis and characterization of these types of catalysts with lower dimensions named as nano-catalysts [18]
