Compounds of formula (I):
and stereoisomers thereof, wherein W is R1O2C-C=CH-ZR2, wherein R1 and R2, which are the same or diffrent, are alkyl or fluoro-alkyl groups, and Z is either an oxygen or sulphur atom; A, B, D and E, which are the same or different, are hydrogen or halogen atoms, or hydroxy, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aralkyl, optionally substituted arylalkoxy, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, optionally substituted aryloxy, optionally substituted arylthio, optionally substituted heteroaryloxy, optionally substituted heteroarylthio, optionally substituted acyloxy, optionally substituted amino, optionally substituted arylazo, optionally substituted acylamino, nitro, cyano, -CO2R3, -CONR3R4, -COR3, -CR3=NR4, -N=CR3R4 or-S(O)nR3 groups; any two of the groups A, B, D and E when they are in adjacent positions on the ring, optionally join to form a fused ring, either aromatic or aliphatic, optionally containing one or more heteroatoms; n is 0, 1 or 2; and R3 and R4, which are the same or different, are hydrogen atoms or alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, optionally substituted aryl or optionally substituted aralkyl groups; and metal complexes thereof.
The compounds are useful in agriculture especially as fungicides but also as insecticides, nematicides and plant growth regulators.
