N-SUBSTITUTED 0-PYRAZOL-4-YL CARBAMATES,PROCESSES FOR THEIR PREPARATION,AND THEIR USE IN PEST-COMBATING AGENTS

摘要

N-substituted O-pyrazol-4-yl carbamates of the general formula (I) are new and are obtained when (a) a 4-hydroxy-pyrazole of the general formula (II) is reacted with an N-sulphenylated carbamoyl halide of the formula (III) or (b) a 4-hydroxy-pyrazole of formula (II) is reacted with an acylating agent of the general formula (IV) or (c) an O-pyrazol-4-yl carbamate of the general formula (V) is reacted with a sulphenyl halide of the general formula R7-(S)n-Y (VI) The new N-substituted O-pyrazol-4-yl carbamates of the formula (I) are distinguished by high activity as pest-combating agents, in particular by high insecticidal and nematicidal activity.
