Abstract
Compounds of the formula ##STR1## in which R.sub.1 is hydrogen, halogen, methyl, methoxy or trifluoromethyl; n is 1 or 2; R.sub.2 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.3 alkyl which is substituted by halogen, cyano or methoxy, or is C.sub.2 -C.sub.5 alkenyl, C.sub.2 -C.sub.5 alkynyl, benzyl, COR.sub.5, CON(R.sub.5)R.sub.6, CSN(R.sub.5)R.sub.6, CO(OR.sub.6), CO(SR.sub.6), CS(SR.sub.5), SO.sub.2 R.sub.7, PO(OR.sub.6).sub.2 or Si(R.sub.6).sub.3 ; R.sub.3 and R.sub.4 independently of one another are hydrogen, C.sub.1 -C.sub.5 alkyl, CH.sub.2 OR.sub.6, cyclopropyl, methylcyclopropyl, C.sub.2 -C.sub.5 alkenyl, C.sub.2 -C.sub.5 alkynyl or C.sub.1 -C.sub.2 haloalkyl; R.sub.5 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.3 alkyl which is substituted by 1 to 3 halogens, C.sub.1 -C.sub.3 alkyl which is substituted or OR.sub.6 or SR.sub.6, or is C.sub.2 -C.sub.5 alkenyl, C.sub.2 -C.sub.5 alkenyl which is substituted by 1 to 3 halogens, C.sub.2 -C.sub.5 alkynyl, C.sub.3 -C.sub.6 cycloalkyl, phenyl or phenyl which is monosubstituted to trisubstituted by halogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 haloalkyl, C.sub.1 -C.sub.3 alkoxy, nitro or cyano; R.sub.6 is C.sub.1 -C.sub.6 alkyl; R.sub.7 is C.sub.1 -C.sub.3 alkyl, phenyl, phenyl which is monosubstituted or disubstituted by halogen, C.sub.1 -C.sub.2 alkyl, C.sub.1 -C.sub.2 haloalkyl, methoxy or nitro; including the acid addition salts, have valuable microbicidal properties. The novel active substances can be employed in crop protection for preventing crop plants being attacked by phytopathogenic microorganisms, and for controlling these pests.
