  • Tosylates or activated halides can be oxidized with DMSO to aldehydes and ketones (Kornblum oxidation). ɑ-Bromo ketones are oxidized at room temperature to ɑ-keto aldehydes: J. Am .Chem. Soc., 79, 6562 (1957). Benzylic halides, on heating in the presence of NaHCO3, give benzaldehydes: J. Am. Chem. Soc., 114, 6227 (1992). Under similar conditions at 150oC, primary alkyl iodides: J. Chem. Soc., 520 (1964), and alkyl chlorides and bromides in the presence of NaI: Synth. Commun., 16, 1343 (1986), are oxidized to aldehydes. Unactivated bromides have also been oxidized to aldehydes in the presence of Ag salts: Tetrahedron Lett., 917 (1974). For oxidation of benzyl alcohols to benzaldehydes, catalyzed by HBr, see: Synlett, 2041 (2002). DMSO is more often used in combination with a variety of activating agents for selective oxidation of primary and secondary alcohols to carbonyl compounds under very mild conditions. For examples, see: Oxalyl­ chloride, A18012, or Trifluoroacetic anhydride, A13614 (Swern oxidation), Acetic anhydride, L04295 (Albright-Goldman), N,N'-Dicyclohexyl­carbodiimide, A10973 (Pfitzner-Moffatt), Sulfur trioxide-pyridine complex, A12202 (Parikh-Doering), Triphosgene, A14932 and Phenyl­ phosphorodichloridate, A10479.
