摘要:
The present invention relates to new substituted hydroxy-malonic acid amide-thioamides of the formula (I) ##STR1## in which R represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl, optionally substituted aryl or optionally substituted heteroaryl,and a process for their preparation and their use as agents for combating pests, in particular insecticides and acaricides.
摘要:
A cyanohydrin phosphate of the formula ##STR1## wherein R represents a hydrogen atom or an optionally substituted radical selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aralkyl, aralkenyl and aryl, or an optionally substituted heterocyclic radical,R.sup.1 and R.sup.2 are identical or different and individually represent optionally substituted radicals selected from alkyl, alkenyl, alkynyl, aryl, aralkyl, alkoxy, aryloxy, aralkoxy, alkylthio, alkenylthio, alkinylthio, arylthio, aralkylthio, alkylamino (monoalkylamino or dialkylamino), arylamino and aralkylamino, or together represent alkanediyl, alkanedioxy, aminoalkyloxy or alkanediamino, andX represents oxygen or sulphur,are obtained by the reaction of a phosphoric acid chloride of the general formula ##STR2## wherein X, R.sup.1 and R.sup.2 have the meaning given above, with an aldehyde of the general formulaR--CHO (III)wherein R has the meaning given above, in the presence of an approximately equimolar quantity of water-soluble cyanides. Some of the compounds of the formula (I) are new. They can be used as insectides and acaricides.
摘要:
O-(2,2,2-trihalogenoethyl) S-alkyl (di)thiophosphonates of the formula ##STR1## in which X is oxygen or sulphur,Y is halogen,R.sup.1 is alkyl or optionally substituted aryl, andR.sup.2 is alkyl.which exhibit insecticidal, acaricidal and nematocidal activity. Intermediates therefor of the formulas ##STR2## in which Z is one equivalent of an alkali metal or ammonium ion, andR.sup.3 is C.sub.1 -C.sub.4 -alkyl, are also new.
摘要:
2-Phenyl-alk-1-enyl-cyclopropane-carboxylic acid esters of the formula ##STR1## in which R each independently is hydrogen, halogen, cyano, nitro and, in each case optionally halogen-substituted, alkyl, alkoxy, alkylenedioxy or alkylthio,R.sup.1 is optionally halogen-substituted alkyk, andR.sup.2 is a radical customary in the alcohol part of pyrethroidswhich exhibit insecticidal and acaricidal activity. They are made from the corresponding alkyl esters which are new and made by novel processes.
