摘要:
New pyrazol-4-yl N-alkylcarbamates of the general formula ##STR1## in which R.sup.1 represents an optionally substituted alkyl group having more than one carbon atom or an alkenyl, alkinyl or cycloalkyl group, andR.sup.2 represents an optionally substituted alkyl,alkenyl, alkinyl, cycloalkyl, aralkyl or aryl group, can be obtained if a 4-hydroxypyrazole of the general formula ##STR2## is reacted with an isocyanate of the general formulaR.sup.1 --N.dbd.C.dbd.O (III)or with a carbamoyl halide of the general formulaR.sup.1 --NH--CO--Hal (IV).The new compounds are distinguished by a high degree of activity as pest-combating agents, in particular by their insecticidal and nematicidal activity.

摘要:
N,N-dimethyl O-(1-carbamoyl-pyrazol-5-yl) carbamates of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3, independently of one another, represent a hydrogen atom or an optionally substituted alkyl group, andR.sup.4 represents an alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl group,are new and are obtained when a 5-hydroxy-pyrazole of the general formula ##STR2## or an alkali metal salt or alkaline earth metal salt thereof, is reacted with an N,N-dimethyl-carbamic acid-halide of the general formula ##STR3## in which Hal represents a chlorine or bromine atom.
