Abstract

Abstract: Hexamethyl-and hexaethylbenzene are oxidized by peroxytrifluoroacetic acid- boron fluoride to hexa-alkyl-2, 4-cyclohexadienones 1 and 2, respectively. The dienones do not dimerize, but 1 gives Diels-Alder adducts with maleic anhydride and other dienophiles. The enolate anion of 1 is much more easily formed at the C-3 methyl than at the C-5 methyl, which enables these methyls to be selectively deuterated. Reaction of 1 with ...
