| titleOfInvention | Method for producing 1,4-benzoquinones |
| abstract | The present invention provides an efficient method for producing a 1,4-benzoquinone compound that is extremely useful as a synthetic intermediate for pharmaceuticals, agricultural chemicals, and the like. A phenol represented by the formula (A) is reacted in an alcohol solvent, preferably an ethanol solvent, in the presence of a copper halide and a hydroxylamine compound, at a reaction temperature of 0 ° C to 90 ° C, preferably 20 ° C. Corresponding 1,4-benzoquinones are produced by oxidation with hydrogen peroxide at -30 ° C. [Wherein, X represents hydrogen or a hydroxyl group, and R 1 , R 2 , R 3 , and R 4 represent hydrogen and an alkyl group, an alkoxy group, an alkylsulfonyl group, an aryl group, an aryloxy group that may have a substituent. And a group independently selected from the group consisting of a group, an arylsulfonyl group, an aralkyl group, a hydroxyl group and a halogen. ] [Selection figure] None |
