METHOD FOR PRODUCING 1,4-BENZOQUINONES
Document Type and Number:
Japanese Patent JP2014189487
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing a 1,4-benzoquinone compound which is extremely useful as a synthetic intermediate of a medicine or an agrochemical or the like.SOLUTION: There is produced corresponding 1,4-benzoquinones by oxidation with hydrogen peroxide of phenols represented by the formula (A) in an alcohol solvent, preferably in an ethanol solvent at a reaction temperature of 0 to 90°C, preferably 20 to 30°C in the presence of a copper halide and a hydroxylamine compound. [wherein, X represents a hydrogen atom or a hydroxyl group; R, R, Rand Reach independently represents a group selected from the group consisting of a hydrogen atom, an alkyl group, an alkoxy group, an alkylsulfonyl group, an aryl group, an aryloxy group, an arylsulfonyl group, an aralkyl group and a hydroxyl group which may have a substituent and a halogen atom.]
