摘要:
Pesticidally active N,N-dimethyl-carbamic acid O-(2-substituted-4,6-dihydro-2H-thieno[3,4-c] pyrazol-3-yl esters or 5-oxides or 5,5-dioxides thereof of the formula ##STR1## in which R is an alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl or aryl radical, andn is 0, 1 or 2.The hydroxypyrazoles corresponding to such esters are also novel.
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.
