An efficient organocatalytic route has been developed to synthesize novel substituted thioxanthenes (2a–2v) starting from diaryl thioether alcohols (1a–1v) using the intramolecular Friedel–Crafts reaction. The starting materials were obtained in two stage

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.

Diaryl sulfoxides bearing ortho-sulfur substituents react readily with Grignard reagents on the sulfur atom to produce the corresponding phenyl Grignard reagents bearing ortho-sulfur functional group.Furthermore, thianthrene monooxide was found to react with alkyl Grignard reagents affording o,o'-bis-Grignard reagent of diphenyl sulfide which was converted easily to Martin's sulfurane.
Stereochemistry of 9-Arylthioxanthene 10-Oxides and 10,10-Dioxides

, p. 3471 - 3482 (2007/10/02)
The stereochemistry of 9-arylthioxanthene 10-oxides and 10,10-dioxides was determined by detailed investigation of the 1H-NMR spectra.These sulfoxides and sulfones were synthesized by oxidation of the corresponding 9-arylthioxanthenes with m-ch
