PROCESS FOR THE PREPARATION OF BIS-TRIAZOLYL STILBENES

Process for the preparation of bis-triazolylstilbene compounds which, in the form of the free acid, correspond to the formula wherein the phenyl radicals A can be substituted by halogen, C1-C4-alkyl or C1-C4-alkoxy, from bis-hydroxyiminohydrazonostilbene compounds of the formula characterized in tha...
