Hudlicky, Oxidations in Organic Chemistry, ACS Monograph 186, Washington DC (1990). Oxidizes silyl enol ethers to ɑ-acetoxycarbonyl compounds in high yields: Tetrahedron, 39, 861 (1983). In combination with a metal halide, enol ethers are similarly converted to ɑ-halocarbonyl compounds: Synthesis, 1021 (1982).
  • Cleaves vic-glycols to carbonyl compounds; see, e.g.: Org. Synth. Coll., 4, 124 (1963).
  • N-Formylanilines are oxidized to isocyanates. In the presence of methanol, the reaction affords the methyl urethanes directly: Synthesis, 225 (1982).
  • Carboxylic acids undergo oxidative decarboxylation; review: Org. React., 19, 279 (1972). In the presence of LiCl, the alkyl chloride is obtained (Kochi reaction): J. Am. Chem. Soc., 87, 2500 (1965); Synth. Commun., 20, 1011 (1990). Yields are lower for the bromide and iodide, cf Hunsdiecker reaction (see Mercury(II) oxide, A16157). Use of NCS allows successful scale-up: Synthesis, 493 (1973).
  • Intramolecular oxidative cyclization of alcohols with the reagent leads to tetrahydrofurans or tetrahydropyrans, a useful method for the functionalization of remote positions; review: Synthesis, 279 (1970). For a review of the hypoiodite method for the functionalization of remote positions such as the angular methyl groups of steroids, e.g. by reaction with lead tetraacetate and iodine, see: Synthesis, 501 (1971). For use in the synthesis of protoadamantane, see: Org. Synth. Coll., 6, 958 (1988). Compare Iodosobenzene diacetate, B24531.

  • For use in dichloroacetic acid for the plumbation of activated aromatics to form aryllead(IV) triacetates, which are useful arylating agents for active methylene groups under very mild conditions, see: Org. Synth. Coll., 7, 229 (1990). For N-arylation of amides, see: J. Org. Chem., 61, 5865 (1996). Arylboronic acids also give aryllead(IV) triacetates, used in situ for electrophilic arylation: J. Chem. Soc., Perkin 1, 715 (1990). For a review of the use of organolead(IV) triacetates in synthesis, see: Pure Appl. Chem., 68, 819 (1996).
