SUBSTITUTED AZOLYL-TETRAHYDRO-FURAN-2-YLIDENE-METHANE DERIVATIVES

摘要

Azolyl-tetrahydrofuran-2-ylidene-methanes useful as fungicides of the formula (I) in which A represents a nitrogen atom or the CH group; X represents oxygen, sulphur or the SO or SO2 group; R represents optionally substituted aryl; R1 to R6 are identical or different and represent hydrogen, alkyl, halogenoalkyl or halogen, a maximum of up to 3 substituents representing halogen or halogenalkyl, with the proviso that R1 and R2 are not at the same time methyl if X represents oxygen; R1 and R2, together with the carbon atom to which they are bonded, represent optionally substituted cycloalkyl or R2 and R3, together with the carbon atoms to which they are bonded, represent optionally substituted cycloalkyl, or addition products thereof with acids or metal salts. Some new intermediates are also shown.
