概要
- 論文の詳細を見る
The treatment of 3,6-dibromo-, 3,7-dibromo, 4,6-dibromo-, and unsubstituted 5-hydroxytropolones with silver acetate in acetone gave the corresponding <I>p</I>-tropoquinones in good yields. When this reaction was carried out in protic solvents, some of these tropoquinones underwent further attack by solvent nucleophiles to give Michael-adducts or ring-contracted cyclohexadienones.
