{ALF} With excess reagent, oxidation of the isoxazoline to the isoxazole occurs.

{ALF} Undergoes an interesting insertion reaction with diarylcyclopropanes: Chem. Lett., 233 (1988):

{ALF}

{ALF} Crystalline nitrosating agent: Secondary amines to nitrosamines: Chem. Ber., 89, 2374 (1956); deamination of primary amides: J. Org. Chem., 30, 2386 (1965); conversion of arylhydrazines to azides: Tetrahedron Lett., 28, 5091 (1987). In organic solvents, converts arylamines directly to diazonium tetrafluoroborates which undergo the Balz-Schiemann reaction (see Tetrafluoroboric acid, L14037) in situ to give high yields of aryl fluorides: Chem. Ber., 88, 1939 (1955); EP 430,434 (1991). Methyl or methoxy substituted aromatics in acetonitrile give the nitrosoaromatics in good yield: J. Org. Chem., 59, 5573 (1994).

{ALF} Convenient catalyst for iodination of aromatics by iodide ion with air as oxidant: J. Org. Chem., 53, 3548 (1988), or for addition of iodine (or iodine + nucleophile) to alkenes: Acta Chem. Scand. B, 43, 902 (1989).
