    • Compounds of the formula I
      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
      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 1 , SR 2 and N(R 3 )R 4 ; R 1 to R 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 3 and R 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.
