Abstract

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 R1 represents a substituted or unsubstituted C1-6 alkylsulfonyl group; R2 represents a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, or the like; A1 represents an oxygen atom, a sulfur atom, or the like; A2 and A3 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

1 . A compound of 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, a substituted or unsubstituted C3-8 cycloalkyl group, a substituted or unsubstituted C6-10 aryl group, a substituted or unsubstituted 5- to 6-membered heteroaryl group, or a halogeno group;
A 1 represents an oxygen atom, a sulfur atom, or NR 3 ;
R 3 represents a hydrogen atom or a C1-6 alkyl group;
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, a substituted or unsubstituted C2-6 alkenyloxy group, a substituted or unsubstituted C2-6 alkynyloxy group, a substituted or unsubstituted C1-6 alkylthio group, a substituted or unsubstituted C1-6 alkylsulfinyl group, or a substituted or unsubstituted C1-6 alkylsulfonyl group;
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.

2 . The compound according to claim 1 , a stereoisomer, tautomer or hydrate thereof or a salt of any of these compounds, wherein the formula (II) is formula (I):

wherein R 1 , R 2 , X, and n represent the same meanings as described in the formula (II).

3 . A pest control agent comprising at least one active ingredient selected from the group consisting of a compound according to claim 1 , a stereoisomer, tautomer and hydrate thereof and a salt of any of these compounds.

4 . An insecticide or acaricide comprising at least one active ingredient selected from the group consisting of a compound according to claim 1 , a stereoisomer, tautomer and hydrate thereof and a salt of any of these compounds.

5 . An ectoparasite control agent comprising at least one active ingredient selected from the group consisting of a compound according to claim 1 , a stereoisomer, tautomer and hydrate thereof and a salt of any of these compounds.

6 . An endoparasite control agent or expellant comprising at least one active ingredient selected from the group consisting of a compound according to claim 1 , a stereoisomer, tautomer and hydrate thereof and a salt of any of these compounds.

7 . A soil treatment agent comprising at least one active ingredient selected from the group consisting of a compound according to claim 1 , a stereoisomer, tautomer and hydrate thereof and a salt of any of these compounds.
