Reagent for ɑ-tosyloxylation of various functional groups; review: Synlett, 337 (1990).


Ketones and ß-dicarbonyl compounds give the ɑ-tosyloxy derivatives: J. Org. Chem., 47, 2487 (1982); see also Synth. Commun., 32, 1875 (2002). For a review of the ɑ-functionalization of carbonyl compounds by hypervalent iodine reagents, see: Contemp. Org. Synth., 2, 121 (1995). Reaction rates are increased by sonication: Tetrahedron Lett., 33, 7647 (1992). Flavanones undergo oxidative rearrangement to isoflavones: Synlett, 337 (1990). For a review of the use of the reagent in heterocyclic synthesis, see: Synlett, 221 (1994).


Alkenes are converted to cis-1,2-ditosyloxyalkanes: J. Org. Chem., 49, 2462 (1984). Unconjugated alkenoic acids undergo cyclization to tosyloxy lactones: Tetrahedron Lett., 27, 4557 (1984); alkenedioic acids give bis-lactones with cis stereoselectivity: Tetrahedron Lett., 27, 5437 (1984):


Benzylic alcohols can be oxidized to benzaldehydes in high yield under microwave irradiation: Tetrahedron Lett., 45, 4939 (2004).


Sulfides are oxidized to sulfoxides in high yields: Synth. Commun., 27, 1315 (1997). In refluxing acetonitrile, alkyl amides are converted to amine tosylates: J. Org. Chem., 51, 2669 (1986), giving better yields from long-chain amides than the classical Hofmann and Curtius methods: J. Org. Chem., 53, 5158 (1988).


Can be used as a source of a phenyl group in the Stille coupling with organostannanes: Tetrahedron Lett., 37, 531 (1996).
