- 論文の詳細を見る
Oxidation of 6-methyl-2-phenylbenzofuran with chromium trioxide in acetic acid gave an unusual dimeric oxidation product, 2,2'-dibenzoyloxy-4,4'-dimethylbenzil (II). Structural establishment came from several chemical evidences including an interestion acyl migration from 2,2'-dibenzoyloxy-4,4'-dimethylhydrobenzoin (III) to 2,2'-dimethoxy-4,4'-dimethylhydrobenzoin dibenzoate (IV) during methylation with diazomethane. On the other hand, oxidation of the same benzofuran with Jones' reagent afforded 2-hydroxy-4-methylbenzil (IX). Furthermore, on treatment with chromium trioxide・pyridine complex, the material (II) was recovered quantitatively.
