摘要

Ketone derivatives represented by the general formula (I) <IMAGE> (I) where R is -CH2R1 (where R1 is a hydrogen atom or an alkyl group), a halogen-substituted alkyl group, a cyano-substituted alkyl group, a cyclopropyl group, <IMAGE> (where R2 is a hydrogen atom or an alkyl group and Y is a hydrogen atom or a halogen atom) or <IMAGE> (where R3 is a hydrogen atom, an alkyl group, a phenyl group or a halogen-substituted phenyl group, and Z is a hydrogen atom or a halogen atom), and X is an oxygen atom or a sulfur atom.
