PROCESS FOR THE PREPARATION OF ANTIFUNG COMPOUNDS BASED ON PHENYL GROUP AMOALS AND FUNGICID COMPOSITIONS CONTAINING THEM

摘要

Compositions, useful in particular for the treatment of plant diseases, characterised in that they have the formula (I) in which The sign CYCLE, surrounded by a semicircle, represents, together with the two carbon atoms to which this semicircle is linked, a carbon ring or heterocyclic ring containing at least one unsaturated bond of ethylenic or aromatic character between the two carbon atoms which carry the group IMAGE and the phenyl group, Y is an oxygen or sulphur atom, Z is an NR1 R2 group, R1 and R2, which may be identical or different, represent an alkyl or alkoxy or cycloalkyl radical, these radicals being optionally substituted, or an alkenyl or alkynyl radical, or R1 and R2 together with the nitrogen atom to which they are bonded form a saturated or unsaturated heterocyclic ring, R3, R4 and R5, which may be identical or different, represent a hydrogen or halogen atom, at least one of these radicals R3, R4 and R5 being other than a hydrogen or halogen atom, or represent an optionally substituted amino group or represent an alkyl or alkoxy group or optionally halogenated or hydroxylated alkyl, alkoxy or alkylthio group, and R3 and R4 (in the meta and para position) can together form a single divalent radical with 3 or 4 chain members, containing 1 or 2 non-vicinal oxygen atoms. The compositions containing these compounds and their use as fungicides. IMAGE
