Abstract:
NOVEL HETEROCYCLIC PHOSPHORIC ACID ESTERS ARE DESCRIBED AS WELL AS THEIR MANUFACTURE AND USE AS PESTICIDES. THE NOVEL COMPOUNDS CORRESPOND TO THE GENERAL FORMULA I OR II.
(I) 3-((R-O-)2-P(=X)-S-CH2-)ISOXAZOLE
(II) 5-((R-O-)2-P(=X)-S-CH2-)ISOXAZOLE
IN WHICH R STAND FOR A METHYL OR ETHYL OR ETHYL GROUP AND X STANDS FOR OXYGEN OR SULFUR.
Abstract:
Tertiary phosphine oxides of the formula
WHEREIN R1 and R2 represent identical or different alkyl groups having from 1 to 6 carbon atoms, and R3 represents a phenyl group substituted by 1 to 5 chlorine and/or bromine atoms or the group
IN WHICH X is chlorine and/or bromine, m is 1 to 4, R4 and R5 are hydrogen or alkyl groups having from 1 to 6, carbon atoms, and in formulae I and II n is 1, 2 or 3, and a process for the preparation of the phosphine oxides named and their use as flame retarding agents.
Abstract:
Compounds of the formula I (I) in which R is hydrogen, (subst.) alkyl, cycloalkyl, benzyl, phenylethyl or (subst.) phenyl, R1, R2 and R3 are alkyl and X is oxygen or sulfur are effective insecticides and acaricides and especially suitable for combating plant lice.
Abstract:
Compounds of the formula I (I) in which R is hydrogen, (subst.) alkyl, cycloalkyl, benzyl, phenylethyl or (subst.) phenyl, R1, R2 and R3 are alkyl and X is oxygen or sulfur are effective insecticides and acaricides and especially suitable for combating plant lice.
Abstract:
Compounds of the formula in which R1 is halogen, alkyl, alkoxy, alkylthio, CF3, NO2, CN2, phenoxy, halophenoxy, phenylthio or halophenylthio, R2 is CN or COOR3, R3 is alkyl, alkoxyalkyl or cycloalkyl and n is 0 to 3 are effective insecticides and acaricides and especially ectoparasiticides.
Abstract:
Compounds of the formula I (I) in which R denotes alkyl, R1 denotes alkyl, alkoxy, alkylmercapto, alkylamino or dialkylamino, R2 and R3 independently of one another denote H, alkyl, cycloalkyl, benzyl or furylmethyl, R4 denotes alkyl, alkoxymethyl, alkylmercaptomethyl or phenyl and X denotes oxygen or sulfur, have valuable insecticidal, acaricidal and nematocidal properties.
