摘要

Several diquinones (I, III, V) undergo photochemical and/or thermal rearrangement to dibenzofuranquinones (II, IV, VI). Structure IV has been established by synthesis and unambiguous structures have been assigned to several of its isomers. It is shown that the hydroxyquinone II, and related compounds, undergo fission of the furan ring when dissolved in alkaline solution, the blue colour produced arising from the anion of the resultant o- ...
