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