摘要:
N-substituted O-pyrazol-4-yl carbamates of the general formula ##STR1## are new and are obtained when (a) a 4-hydroxy-pyrazole of the general formula ##STR2## is reacted with an N-sulphenylated carbamoyl halide of the formula ##STR3## or (b) a 4-hydroxy-pyrazole of formula (II) is reacted with an acylating agent of the general formula ##STR4## or (c) an O-pyrazol-4-yl carbamate of the general formula ##STR5## is reacted with a sulphenyl halide of the general formulaR.sup.7 --(S).sub.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.
