摘要:
A benzoylurea derivative represented by the formula, wherein R₁ is a hydrogen atom or a fluorine atom, R₂ is a trifluoromethyl group, a pentafluoroethyl group or a heptafluoropropyl group, and R₃ is a hydrogen atom, a fluorine atom or a chlorine atom, has insecticidal activity and may be formulated into insecticidal compositions. It can be prepared by reaction of a benzoyl isocyanate or benzamide compound providing the benzoyl residue with an aniline or isocyanate compound respectively providing the aniline residue.

The present invention relates to aldehyde compounds represented by the general formula (I)
wherein R₁ and R₂, which may be identical or different, represent a hydrogen or halogen atom or a C₁₋₅ alkyl, C₁₋₅-haloalkyl, C₁₋₅-alkoxyl, C₁₋₅-haloalkoxyl, C₂₋₅-alkenyl or C₂₋₅-alkenyloxyl group, or represent, taken together, a methylenedioxy, C₃₋₄-alkylene, ethyleneoxy or C₁₋₅-alkylethyleneoxy group with the proviso that when R₁ and R₂ are identical they are not hydrogen atoms. These compounds are valuable intermediates for the production of insecticidal and/or acaricidal ether compounds.
