Low-cost chlorinating and oxidizing agent; review: Org. Process Res. Dev., 6, 384 (2002). Aromatic compounds can be chlorinated either on the ring (ionic conditions) or on the side chain (free-radical conditions): J. Org. Chem., 35, 719 (1970). In the presence of BF3 etherate, ketones are ɑ-chlorinated at the more substituted position: Synth. Commun., 15, 385 (1985). In combination with pyridine, sulfides are selectively oxidized to sulfoxides: Synth. Commun., 31, 245 (2001), thiols to disulfides: Synth. Commun, 31, 1825 (2001), and secondary alcohols to ketones: Synth. Commun., 22, 1589 (1992). In the presence of methanol in acetonitrile, acetone or dichloromethane, the same reagent system converts aldehydes directly to methyl esters: Synth. Commun., 26, 2633 (1996). Effective co-oxidant for the TEMPO-catalyzed chemoselective oxidation of alcohols to aldehydes and ketones: Org. Lett., 3, 3041 (2001). In acetic acid, pyridines are converted to their N-oxides: Synth. Commun., 34, 247 (2004).

With NaNO2 and wet silica selective mononitration of phenols is accomplished under mild conditions: Synlett, 191 (2003). Effectively catalyzes both the protection and deprotection of alcohols as their tetrahydropyranyl ethers: Synth. Commun., 34, 3623 (2004).

Note: Confusion with Cyanuric chloride, L03442, exists in some earlier Fieser references.
