1-(2-AMINO-SUBSTITUTED PHENYL)-2-HALO-2,2-DIFLUOROETHANONE COMPOUND, AND METHOD FOR PRODUCING 1-(SUBSTITUTED PHENYL)-2-HALO-2,2-DIFLUOROETHANONE COMPOUND

摘要

[Problem] To provide a novel method for producing a 1-(substituted phenyl)-2-halo-2,2-difluoroethanone compound.[Solution] A method for producing a compound represented by general formula (1) by reacting a compound represented by general formula (2) with a nitrous acid compound.(In general formula (2), each of X¹, X² and X³ independently represents a halogen atom, a C₁-C₆ alkyl group, a C₁-C₆ haloalkyl group, a C₁-C₆ alkoxy group, a C₁-C₆ haloalkoxy group or the like, and Y represents a halogen atom.)(In general formula (1), X¹, X², X³ and Y are as defined above.)
