摘要

A compound of formula I: F1 Het is a 5- or 6-membered heterocyclic ring containing one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, the ring being substituted by groups R4, R5 and R6 R1 is hydrogen or halo R2 is hydrogen or halo R3 is optionally substituted C2-12 alkyl, optionally substituted C2-12 alkenyl, optionally substituted C2-12 alkynyl, optionally substituted C3-12 cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl and R4, R5 and R6 are, independently, selected from hydrogen, halo, cyano, nitro, C1-4 haloalkyl, C1-4 alkoxyl C1-4 alkoxyl C1-4 alkyl and C1-4 haloalkoxy C1-4 alkyl, provided that at least one of R4, R5 and R6 is not hydrogen. The compounds of formula I have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms.
