There is provided a process for producing an amide compound having an excellent harmful arthropod-controlling activity and represented by the formula (3): wherein R, Rand Rindependently represent a C1-C6 alkyl group optionally substituted with at least one halogen atom etc., R, R, Rand Rindependently represent a halogen atom etc.

Process for producing amide compound

There is provided a process for producing an amide compound having an excellent harmful arthropod-controlling activity and represented by the formula (III): wherein R, Rand Rindependently represent a C-Calkyl group optionally substituted with at least one halogen atom etc., R, R, Rand Rindependently represent a halogen atom etc. 

A hydrazide compound represented by the formula (I), an N-oxide thereof or suitable salt thereof: has excellent pesticidal activity. 

Heterocyclic hydrazide compound and pesticidal use of the same

Disclosed is a method for producing an amide compound represented by the formula (3) below and having an excellent control activity against a harmful arthropod, which is characterized in that an aniline compound represented by the formula (1) below and an aldehyde compound represented by the formula (2) below are reacted in a solvent in the presence of an oxidizing agent such as oxygen or a peroxide. (In the formulae below, R, Rand Rindependently represent a C-Calkyl group which may be substituted by a halogen atom, or the like; and R, R, Rand Rindependently represent a halogen atom or the like.) 

Method for producing amide compound

Disclosed is a hydrazine compound represented by the formula (1) below, which has an excellent control activity against a harmful arthropod. (1) (In the formula, R, R, Rand Rrepresent a hydrogen atom or the like; Rand Rare bonded together at their ends to form a 5- to 8-membered ring together with two nitrogen atoms; Rrepresents a halogen atom or the like; J represents 1-(3-chloro-2-pyridyl)-3-bromo-H-pyrazol-5-yl group or the like; and M represents a hydrogen atom, an optionally halogenated C-Calkyl group, or the like.) 

Hydrazide compound and harmful arthropod-controlling agent containing the same

A hydrazide compound represented by the formula (1): (wherein R, R, R, R, A, A, J, Q and n are defined in the specification) has excellent pesticidal activity.

Hydrazide compound and pesticidal use of the same

A hydrazide compound represented by the formula (1): has excellent pesticidal activity.
