AMIDRAZONE COMPOUNDS FOR COMBATING ANIMAL PESTS

摘要

The present invention relates to new amidrazone compounds which are useful for combating animal pests, in particular insects, arachnids and nematodes. The invention also relates to a method for combating insects, nematodes and arachnids. The amidrazone compounds are of the general formula (I) including the tautomers of I and the salts thereof; wherein X and Y are hydrogen or together form a chemical bond; Ar is an aromatic radical selected from phenyl and a 5- or 6-membered heteroaryl having 1 , 2, 3 or 4 heteroatoms as ring members, which are selected, independently of one another, from O, N and S, and where the aromatic radical may have 1 , 2, 3, 4 or 5 substituents R<SUP>a</SUP>; R<SUP>1</SUP> is selected from the group consisiting of C<SUB>1</SUB>-C<SUB>1O</SUB>-alkyl, C<SUB>1</SUB>-C<SUB>4</SUB>-alkoxy-C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, cyano-C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, hydroxy-C<SUB>1-</SUB>C<SUB>4</SUB>-alkyl, C<SUB>1</SUB>-C<SUB>10</SUB>-haloalkyl, tri-(C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl)-silyl-C<SUB>1</SUB>- C<SUB>4</SUB>-alkyl, C<SUB>2</SUB>-C<SUB>10</SUB>-alkenyl, C<SUB>2</SUB>-C<SUB>10</SUB>-haloalkenyl, C<SUB>2</SUB>-C<SUB>10</SUB>-alkynyl, C<SUB>2</SUB>-C<SUB>10</SUB>-haloalkynyl, C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl, phenyl, heteroaryl, C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl-C<SUB>1</SUB>C<SUB>4</SUB>-alkyl, phenyl-C<SUB>1</SUB>-C<SUB>4</SUB>- alkyl and heteroaryl-C<SUB>1</SUB>C<SUB>4</SUB>alkyl, wherein C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl, heteroaryl and phenyl in the last six mentioned radicals may be unsubstituted or carry 1 , 2, 3, 4 or 5 substituents R<SUP>b</SUP> as defined above; R<SUP>2</SUP> is selected from the group consisiting of C<SUB>1-</SUB>C<SUB>1</SUB>0-alkyl, c<SUB>1-</SUB>c<SUB>4</SUB>-alkoxy- C<SUB>1-</SUB>C<SUB>4</SUB>-alkyl, C<SUB>1-</SUB>C<SUB>10</SUB>-haloalkyl, C<SUB>2</SUB>-C<SUB>10</SUB>-alkenyl, C<SUB>2</SUB>-C<SUB>10</SUB>-haloalkenyl, C<SUB>2</SUB>-C<SUB>10</SUB>-alkynyl, C<SUB>2</SUB>-C<SUB>10</SUB>- haloalkynyl,c<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl, phenyl, heteroaryl, C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl-C<SUB>1-</SUB>C<SUB>4</SUB>-alkyl, phenyl-C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl and heteroaryI-C<SUB>1-</SUB>C<SUB>4</SUB>-alkyl, wherein C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl, heteroaryl and phenyl in the last six mentioned radicals may be unsubstituted or carry 1 , 2, 3, 4 or 5 substituents R<SUP>b</SUP> as defined above.
