概要

• 論文の詳細を見る

• 2-Hydroxy-4-methoxy- and 2-hydroxy-4,4′-dimethoxybenzophenones were oxidized to dimeric compounds with lead tetraacetate and with manganic acetate. 2-Hydroxy-2′,4,4′-trimethoxy- and 2-hydroxy-3′,4,4′trimethoxybenzophenones were oxidized to substituted xanthones. The structures of the products were determined by NMR and mass spectra, and were confirmed by syntheses.
