摘要:
2,4-Di-tert-butyl-5,6-dioxocyclohexa-1,3-diene-1-carboxylic acid, an oxidized analogue of sterically hindered pyrocatechuic acid, was obtained from 4,6-di-tert-butyl-2,3dihydroxybenzaldehyde in four stages. The electrochemical reduction of this compound proceeds in two stages: the first reduction wave (Ered1 = ?0.24 V) is irreversible, while the second stage is partially reversible (E1/2, red2 = ?0.65 V). The molecular structure of the o-quinone carboxylic acid in the crystalline state was comfirmed by single-crystal X-ray analysis.
