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.)
