The invention provides thiazole derivatives of the general formula I: ##STR1## or acid-addition salts or metal salt complexes thereof, in which R represents an optionally substituted phenyl group; A represents a group ##STR2## R.sup.1 represents a hydrogen atom or an optionally substituted alkyl, alkenyl or aralkyl group; and R.sup.2 represents a hydrogen or halogen atom or an alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, hydroxyl, cyano, nitro, amino, alkylamino or dialkylamino group; processes for their preparation; compositions containing such compounds and their use as fungicides.

Thiazole derivatives

The invention provides thiazole derivatives of the general formula I: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted phenyl group; R.sup.1 represents a hydrogen atom or an optionally substituted alkyl or phenyl group; R.sup.2 represents a hydrogen atom or an optionally substituted akyl, alkylcarbonyl, alkenyl, cycloalkylcarbonyl or benzyl group; R.sup.3 represents a hydrogen or halogen atom or a haloalkyl, alkoxy, haloalkoxy, alkylthio, hydroxyl, cyano, nitro or dialkylamino group; Y represents a group --CH.sub.2 O-- or --CH.sub.2 CH.sub.2 -- and n is 0 or 1; processes for their preparation; compositions containing such compounds and their use as fungicides.

The invention provides imidazole dioxolane derivatives of the general formula: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted phenyl group; R.sup.1 represents a hydrogen atom or an optionally substituted alkyl or alkenyl group; R.sup.2 represents an optionally substituted alkyl group; and n is 1 or 2; processes for their preparation; compositions containing such compounds and their use as fungicides.

Fungicidal imidazole dioxolane and 1,3-dioxane derivatives

The invention provides imidazole oxime derivatives of the general formula I: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted phenyl group; R.sup.1 represents an optionally substituted alkyl, alkenyl, alkynyl, or aralkyl group; and R.sup.2 represents an optionally substituted alkyl group; processes for their preparation; compositions containing such compounds and their use as fungicides.

Fungicidal imidazole oxime derivatives

The invention provides imidazole ketone derivatives of the general formula I: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents a phenyl group substituted by one or more halogen atoms and R.sup.2 represents an optically substituted alkyl group; processes for their preparation; compositions containing such compounds and their use as fungicides.

Fungicidal imadazole ketone derivatives

The invention provides thiazole derivatives of general formula I; ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted aryl group; R.sup.1 represents a hydrogen atom or an optionally substituted alkyl, alkenyl or alkynyl group; R.sup.2 represents a hydrogen or halogen atom or an alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, hydroxyl, cyano, nitro, amino, alkylamino, dialkylamino or morpholine group; X represents an oxygen or sulphur atom, a carbonyl group or a group --CR.sup.4 R.sup.5 -- where R.sup.4 and R.sup.5 independently represent a hydrogen atom or an alkoxy group; Y represents an oxygen or sulphur atom; n represents an integer from 0 to 6; m is 0 or 1; and Z represents a phenyl group; processes for their preparation; compositions containing such compounds and their use as fungicides.
