  • Abstraction of the ɑ-H atom of alcohols and their O-substituted derivatives results in oxidation to the ketones:
  • Cycloheptatriene gives the tropylium cation: J. Am. Chem. Soc., 79, 4557 (1957).
  • Oxidation of TMS ethers to ketones: J. Org. Chem., 41, 1479 (1976); secondary alcohols to ketones, and secondary diols to ɑ-hydroxy ketones: Tetrahedron Lett., 2771 (1978). Ketones can similarly be oxidized to ɑß-unsaturated ketones by hydride abstraction from their silyl enol ethers: J. Org. Chem., 42, 3961 (1977); Synthesis, 736 (1979).
  • The trityl cation abstracts hydride ion from a variety of substrates:
  • The trityl cation is also useful for the oxidative cleavage of the 4-methoxybenzyl protecting group from secondary alcohols: J. Org. Chem., 49, 51 (1984).
  • With 1,3-Dithiane, A10505, gives the electrophilic dithienium salt which can react with silyl enol ethers to give ɑ-formyl or ɑ-methyl carbonyl compounds: Tetrahedron Lett., 22, 2829, 2833 (1981).
