ABSTRACT:
The present invention relates to carbonate, carbamate, thiocarbonate, dithiocarbonate and thiocarbamate derivatives that are useful as fungicides, to processes for preparing them, to compositions containing them and to methods of using them to combat fungi, especially fungal infections of plants.

is not optionally substituted aryl.
Because the double bond of the propenoate, oxyiminoacetamide or oxyiminoacetate group is unsymmetrically substituted, the compounds of the invention may be obtained in the form of mixtures of (E)- and (Z)-geometric isomers. However, these mixtures can be separated into individual isomers, and this invention embraces such isomers and mixtures thereof in all proportions including those which consist substantially of the (Z)-isomer and those which consist substantially of the (E)-isomer. The (E)-isomers are the more fungicidally active and form a preferred embodiment of the invention.
When W is CH
3
ON═CCONR
3
R
4
it is preferred that R
3
is hydrogen and that R
4
is methyl.
Aryl is preferably phenyl.
Heteroaryl includes 5- and 6-membered aromatic rings containing one or more heteroatoms selected from the list comprising oxygen, sulphur and nitrogen and can be fused to benzenoid ring systems. Examples of heteroaryl are pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, triazinyl, furyl, thienyl, pyrrolyl, pyrazolyl, imidazolyl, triazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, quinolinyl, isoquinolinyl, cinnolinyl, quinazolinyl, quinoxalinyl, indolinyl, isoindolinyl, benzofuranyl, benzothiophenyl and benzimidazolinyl.
Examples of the heterocyclic ring system which can be formed by R
1
and R
2
are pyrrole, pyrrolidine, thiomorpholine, indoline, azetidine, indole, isoindole, imidazole, piperidine, morpholine, benzimidazole and pyrazole. These ring systems are unsubstituted, or substituted as for heteroaryl.
Substitutents which may be present in optionally substituted aryl and heteroaryl moieties include one or more of the following: halo, hydroxy, mercapto, C

All alkyl moieties and the alkyl moiety of alkoxy preferably contain from 1 to 6, more preferably from 1 to 4, carbon atoms. They can be in the form of straight or branched chains, for example methyl, ethyl, n- or iso-propyl, or n-, sec-, iso- or tert-butyl.
Alkenyl and alkynyl moieties preferably contain from 2 to 6, more preferably from 2 to 4, carbon atoms. They can be in the form of straight or branched chains, and the alkenyl moieties, where appropriate, may have either the (E)- or (Z)-configuration. Examples are vinyl, allyl and propargyl.
Halogen is typically fluorine, chlorine or bromine.
