    摘要： Compounds of the formula I ##STR1## and disulfides thereof and salts thereof are important intermediate products for the preparation of compounds having a microbicidal and plant-immunizing action, of the formula III ##STR2## In the compounds of the formulae 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.sub.1, SR.sub.2 and N(R.sub.3)R.sub.4 ; R.sub.1 to R.sub.4 are hydrogen, a substituted or unsubstituted, open-chain, saturated or unsaturated hydrocarbon radical containing not more than 8 carbon atoms, a substituted or unsubstituted cyclic, saturated or unsaturated hydrocarbon radical containing not more than 10 carbon atoms, substituted or unsubstituted benzyl or phenethyl, a substituted or unsubstituted alkanoyl group containing not more than 8 carbon atoms, a substituted or unsubstituted benzoyl group or a substituted or unsubstituted heterocyclyl radical; or R.sub.3 and R.sub.4, together with the nitrogen atom to which they are bonded, are a 5- or 6-membered, substituted or unsubstituted heterocyclic radical having 1-3 heteroatoms O, S and/or N. Processes for the preparation of compounds of the formula I are described.
