Dihalopropene compounds, process for their preparation, compositions comprising them and their use as pesticides What is described are dihalopropene compounds of the formula (I) in which R<SUP>1 </SUP>and R<SUP>2 </SUP>are halogen, Y is -O-, -S- or -NH-, X is -O-, -S(O)<SUB>r</SUB>- or -NR<SUP>5</SUP>- (where r=0, 1, 2 and R<SUP>5 </SUP>is hydrogen or C<SUB>1</SUB>-C<SUB>8</SUB>-alkyl), X' is a direct C-C bond, -O-, -S(O)<SUB>r</SUB>- or -NR<SUP>5</SUP>- (where R<SUP>5 </SUP>is as defined above), R<SUP>3 </SUP>is hydrogen, halogen, nitro, cyano, C<SUB>1</SUB>-C<SUB>8</SUB>-alkyl, C<SUB>1</SUB>-C<SUB>8</SUB>-haloalkyl, C<SUB>1</SUB>-C<SUB>8</SUB>-alkoxy, C<SUB>1</SUB>-C<SUB>8</SUB>-haloalkoxy, C<SUB>3</SUB>-C<SUB>10</SUB>-cycloalkyl or has one of the meanings defined for A, A has the meaning given in the description (inter alia aryl, heterocyclyl), B is a divalent bridge having the meanings given in the description (inter alia alkylene) and R<SUP>4 </SUP>is a monovalent C<SUB>6</SUB>-C<SUB>14</SUB>-aryl radical or nitrogen-containing heteroaryl radical having at least one ring heteroatom which has the meanings given in the description. These compounds can be used for preparing pesticides. |
