A green synthesis of unsymmetrical 9-arylxanthenones is described using Ca(OTf)2 in one-pot cascade benzylation, annulation and dehydration strategy starting from readily accessible π-activated carbinols. 4-Hydroxycoumarin/cyclohexane-1,3-dione

An expeditious and highly practical, microwave assisted benzylation of naphthols and 4-hydroxycoumarin has been developed under catalyst-free & solvent-free conditions. Alcohols undergo heat induced dehydration to form ethers, which collapse reversibly to form the carbocation which was captured immediately by a suitable nucleophile to furnish the benzylated compounds.

A. facile and general three-step synthetic route towards unsymmetrical 9-arylxanthenes was developed. The reaction sequence involves nucleophilic substitution of commercially available 2-fluorobenzaldehydes with arenoxides, Grignard reaction of the resulting 2-arenoxybenzaldehydes with arylmagnesium bromides, followed by FeCl3-catalyzed intramolecular diarylmethylation of the resulting carbinols, This strategy was extended to access symmetrical as well as unsymmetrical 9-arylthioxanthenes.

The rearrangement of diphenylmethanol (3) to the corresponding fuchsone (4) has been shown to proceed in the solid state (either as a reaction of powders or syngle crystals)when induced thermally or photothermally.The thermal reactio
