PROCESS FOR THE PREPARATION OF 1,2,3-TRIADIAZOL-3-IN-5-ILIDENE-Urea DERIVATIVES AND GROWTH-REGULATING AND DEFOLIATING COMPOSERS

摘要

New 1,2,3-thiadiazol-3-in-5-yliden-urea derivatives are disclosed of the general formula IMAGE in which R1 is hydrogen or an, if necessary, interrupted one or more times oxygen or sulfur atom, C1-C4-alkyl group, R2 is an, if necessary interrupted one or more times by oxygen or sulfur atoms C1-C4-alkyl group, an, if necessary, substituted one or more times by alkyl C3-C8 cycloalkyl group, an, if necessary, substituted one or more times by alkyl and/or halogen and/or alkylthio and/or alkoxy and/or trifluoromethyl and/or nitro aromatic hydrocarbon group or an, if necessary, substituted heterocyclic, at least one N-atom-containing, hydrocarbon group or R1 and R2 together with the N-atom are morpholino-, piperidino- or pyrolidino, R3 is an, if necessary, substituted C1-C10-alkyl group, a C2-C6-alkenyl, or C3-C6-alkenyl group, or an, if necessary, substituted aryl-C1-C2-alkyl group and X is an oxygen or a sulfur atom, as well as its acid addition salt with inorganic and organic acid. Also disclosed are processes for the production of these compounds and compositions containing the same and having growth-regulatory and defoliating activity.
