- 論文の詳細を見る
Oxidation of 7-hydroxy-2,3-diphenylbenzofuran (III) with Fremy's salt, [ON (SO_3K)_2], gives 4,7-dihydro-2,3-diphenylbenzofuran-4,7-dione (IX), mp 240-241°, (yield 40%) and 6,7-dihydro-2,3-diphenylbenzofuran-6,7-dione (X), mp 160-161°, (yield >40%). Oxidation of 7-hydroxy-2,3-diphenylbenzo [b] thiophene (IV) with the same reagent affords 4,7-dihydro-2,3-diphenylbenzo [b] thiophene-4,7-dione (XXII), mp 162-163°, (yield 14.2%) and 6,7-dihydro-2,3-diphenylbenzo [b] thiophene-6,7-dione (XXIII), mp 202-203.5°, (yield 45.5%).
