- METHOD FOR PRODUCING PHENOLIC COMPOUND
-
Provided is a method for producing a compound represented by formula (2-b), which is useful as an intermediate for producing agricultural chemicals. The method includes a step for obtaining a compound represented by formula (2-a) by oxidizing the compound represented by formula (1) with hydrogen peroxide in the presence of sulfuric acid and/or a C1-6 alkanesulfonic acid that may be halogen-substituted and in the presence of a C2-12 aliphatic carboxylic acid and/or sulfolane. The method also includes a step for obtaining a compound represented by formula (2-b) by nitrating a compound represented by formula (2-a) in the presence of sulfuric acid and/or a C1-6 alkanesulfonic acid that may be halogen-substituted.

- Thia-Fries rearrangement of aryl triflinates to trifluoromethanesulfinylphenols
-
Aryl triflinates are transformed to trifluoromethanesulfinylphenols in the presence of aluminum trichloride in dichloromethane at room temperature according to a thia-Fries rearrangement process. Rigorous exclusion of oxygen is necessary in order to avoid the formation of 2,2′-dihydroxybiaryls as secondary products.
