Method for producing [alpha]-halogenoacetophenon compound, and [alpha]-bromoacetophenon compound

A method for producing an [alpha]-halogenoacetophenon compound comprises reacting a specific [alpha]-halogenocarboxylic halide compound with a specific phenyl compound in a solvent in the presence of a Lewis acid, wherein the Lewis acid and the specific phenyl compound are reacted at a molar ratio that meets the requirement represented by the following formula: 2 = (Lewis acid)/(phenyl compound) = 6

METHOD FOR PRODUCING ALPHA-HALOGENOACETOPHENON COMPOUND, AND ALPHA-BROMOACETOPHENON COMPOUND

A method for producing an α-halogenoacetophenon compound includes reacting a specific α-halogenocarboxylic halide compound and a specific phenyl compound in the presence of a Lewis acid in a solvent, in which the α-halogenoacetophenon compound and the phenyl compound are reacted with each other in a molar ratio of the Lewis acid to the phenyl compound represented below.
