Title: Heterocyclic compounds
Abstract:Triazole and imidazole compounds having the general formula (I): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, are hydrogen, alkyl, optionally unsubstituted cycloalkyl, cycloalkylmethyl, alkenyl, heterocyclyl, aryl or aralkyl optionally substituted with halogen, nitro, alkyl, haloalkyl, haloalkoxy, alkoxy, phenyl, phenoxy, benzyl, benzyloxy, halophenyl or haloalkoxy, R.sup.3 is hydrogen, alkyl, alkenyl, alkynyl, aralkyl or acyl; R.sup.4 and R.sup.5, which may be the same or different, are hydrogen, alkyl, alkenyl or optionally substituted aryl; R.sup.6 and R.sup.7, which may be the same or different, are hydrogen, alkyl, alkenyl or optionally substituted aryl; X is oxygen or sulphur or is SO or SO.sub.2 ; and Az is a 1,2,4- or 1,3,4-triazole or imidazole ring; and isomers, acid addition salts and metal complexes thereof. These compounds possess fungicidal activity against fungal infection in plants.
Inventor(s): Worthington; Paul A. (Maidenhead, GB2)
Assignee: Zeneca Limited (London, GB2)
Filing Date:Feb 22, 1985
Application Number:06/704,216
