Abstract
Compounds of formula ##STR1## wherein: R.sub.1 is phenyl, naphthyl, phenyl substituted from one to five times by R.sub.6, or naphthyl substituted from one to five times by R.sub.6 ; R.sub.2 is C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkyl substituted at least once by halogen, C.sub.1 -C.sub.3 alkoxy and/or by C.sub.3 -C.sub.6 cycloalkyl, C.sub.3 -C.sub.6 cycloalkyl, C.sub.1 -C.sub.4 alkoxycarbonyl, phenyl, phenyl mono- to tri-substituted by halogen, C.sub.1 -C.sub.3 alkoxy and/or by C.sub.1 -C.sub.3 alkyl, benzyl, or benzyl mono- to tri-substituted by halogen, C.sub.1 -C.sub.3 alkoxy and/or by C.sub.1 -C.sub.3 alkyl; R.sub.3 is hydrogen, C.sub.1 -C.sub.6 alkyl or the radical CO-R.sub.7 ; R.sub.4 is C.sub.3 -C.sub.6 cycloalkyl, C.sub.3 -C.sub.6 cycloalkyl mono- to tri-substituted by halogen and/or by methyl, C.sub.1 -C.sub.4 alkyl substituted at least once by halogen, hydroxy and/or by cyano, C.sub.2 -C.sub.5 alkynyl, C.sub.1 -C.sub.4 alkylthio or the radical CH.sub.2 XR.sub.8 ; R.sub.5 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkyl substituted at least once by halogen, hydroxy, cyano and/or by C.sub.1 -C.sub.3 alkoxy, R.sub.5 is also C.sub.3 -C.sub.5 alkenyl, halogen, hydroxy, C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.3 haloalkoxy, C.sub.3 -C.sub.6 cycloalkyl or C.sub.1 -C.sub.3 alkylthio; R.sub.6, independently of any other, is C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.3 alkyl substituted by C.sub.1 -C.sub.3 alkoxy, or C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.3 haloalkyl, C.sub.1 -C.sub.3 haloalkoxy, halogen, cyano, nitro, hydroxy or the radical S(O).sub.n -C.sub.1 -C.sub.4 alkyl; R.sub.7 is C.sub.1 -C.sub.6 alkyl, or C.sub.1 -C.sub.6 alkyl substituted at least once by halogen and/or by C.sub.1 -C.sub.3 alkoxy; R.sub.8 is C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkyl substituted at least once by halogen, hydroxy, cyano and/or by C.sub.1 -C.sub.4 alkoxy, C.sub.3 -C.sub. 6 alkenyl, C.sub.3 -C.sub.6 alkynyl or C.sub.3 -C.sub.6 cycloalkyl; X is oxygen or sulfur; and n is 0, 1 or 2; including the acid addition compounds and the metal salt complexes thereof, have valuable microbicidal properties. The novel compounds can be used in plant protection for preventing attacks on cultivated plants by phytopathogenic microorganisms and for controlling those microorganisms.
