Abstract

Official abstract text for this publication.

An object of the present invention is to provide a pyridine N-oxide compound that is excellent in pest control activity, particularly, insecticidal activity and/or acaricidal activity, is excellent in safety, and may be industrially advantageously synthesized. The pyridine N-oxide compound of the present invention is a compound of the formula (II), a stereoisomer, tautomer or hydrate thereof or a salt of any of these compounds, wherein R 1 represents a substituted or unsubstituted C1-6 alkylsulfonyl group; R 2 represents a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, or the like; A 1 represents an oxygen atom, a sulfur atom, or the like; A 2 and A 3 each independently represent a carbon atom or a nitrogen atom; X represents a substituted or unsubstituted C1-6 alkyl group, a substituted or unsubstituted C1-6 alkoxy group, or the like; and n represents an integer of 0 to 2.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compound of formula (I), a stereoisomer, tautomer or hydrate thereof or a salt of any of these compounds: wherein R 1 represents a C1-6 alkylsulfonyl group; R 2 represents a C3-8 cycloalkyl group; X represents a C1-6 alkylthio group which is unsubstituted or substituted with a halogen, a C1-6 alkylsulfinyl group which is unsubstituted or substituted with a halogen, or a C1-6 alkylsulfonyl group which is unsubstituted or substituted with a halogen; n represents a number of chemically acceptable Xs, and is an integer of 0 to 2; and Xs are the same or different when n is 2.
