titleOfInvention | Method for producing nitrohalogenoacetophenone derivative |
abstract | (57) [Summary] [Objective] An object of the present invention is to provide a method for producing a nitrohalogenoacetophenone derivative capable of nitrating a halogenoacetophenone derivative in a much higher yield than the conventional mixed acid method of nitric acid and sulfuric acid. Is provided. [Structure] The halogenoacetophenone derivative represented by the general formula (I) is represented by: (R 1 , R 2 and R 3 represent hydrogen or a halogen atom, It may be the same. However, at least one of R 1 , R 2 and R 3 contains a halogen atom, R 4 represents a hydrogen atom, a halogen atom, an alkyl group, an amino group and an alkoxy group, n is an integer of 1 to 4, and n And R 4 are 2 to 4, R 4 may be the same or different. ) A method for producing a nitrohalogenoacetophenone derivative, which comprises performing the reaction in the presence of sulfur trioxide or an acid containing sulfur trioxide during nitration with nitric acid. |
