Disclosed are compounds of formula (I) and their disulfides and salts, which are important intermediate products for the preparation of compounds with microbiocidal effects for the immunization of plants of formula (III). In compounds of formulas (I) and (III), X is halogen, n is 0, 1, 2, or 3, Z is CN, CO-A or CS-A, A is hydrogen, halogen, OR 1, SR 2 or N ( R3) R4, and R1 to R4 are each hydrogen, a substituted or unsubstituted, saturated or unsaturated, open chain hydrocarbon group containing no more than 8 carbon atoms, a substituted or unsubstituted cyclic, saturated or unsaturated hydrocarbon group containing no more than 10 carbon atoms , a substituted or unsubstituted benzyl or phenethyl group, a substituted or unsubstituted alkanoyl group containing not more than 8 carbon atoms, a substituted or unsubstituted benzoyl group, or a substituted or unsubstituted heterocyclic radical, or R 3 and R 4 together with the nitrogen atom to which they are attached, represents a 5- or 6-membered, substituted or unsubstituted heterocyclic residue containing 1 to 3 heteroatoms which are oxygen, sulfur and / or nitrogen. Also described is a process for the preparation of compounds of formula (I) and intermediates |
