Abstract

Dihalopropene compounds, process for their preparation, compositions comprising them and their use as pesticidesWhat is described are dihalopropene compounds of the formula (I) in which R1 and R2 are halogen, Y is —O—, —S— or —NH—, X is —O—, —S(O)r— or —NR5— (where r=0, 1, 2 and R5 is hydrogen or C1-C8-alkyl), X′ is a direct C—C bond, —O—, —S(O)r— or —NR5— (where R5 is as defined above), R3 is hydrogen, halogen, nitro, cyano, C1-C8-alkyl, C1-C8-haloalkyl, C1-C8-alkoxy, C1-C8-haloalkoxy, C3-C10-cycloalkyl or has one of the meanings defined for A, These compounds can be used for preparing pesticides.
