    Abstract: The invention comprises 2,3-dimercapto-quinoxalines of the general formula: wherein R represents a hydrogen or halogen atom or a nitro, trifluoromethyl, C1-C4 alkyl or C1-C4 alkoxy radical; R1 represents a hydrogen atom or a hydroxy, alkyl, cycloalkyl, aryl, chloroaryl, aralkyl, alkylsulphonyl, arylsulphonyl or primary or secondary amino radical; and R2 represents a hydrogen atom or an acyl, alkyl, cycloalkyl, aralkyl, aryl, alkoxy, alkylmercapto, arylmercapto or a primary or secondary amino radical. They may be prepared by reacting a 2,3-dimercapto-quinoxaline of the general formula: or an alkali metal or ammonium salt thereof, with a compound of the general formula: in an aqueous or aqueous organic medium at -20 DEG to + 100 DEG C. and preferably in the presence of an acid-binding agent. The compounds of the formula: wherein R1 and R2 represent alkyl, cycloalkyl, aryl, chloroaryl or aralkyl radicals, may also be prepared by reacting the 2,3-dimercapto-quinoxaline starting material specified above with two molecules of a carbodiimide of the general formula: R1-N=C=N-R2. Several examples are given and the compounds of the invention are stated to be pest control agents (see Division A5).ALSO:Compounds of the general formula wherein R represents a hydrogen or halogen atom or a nitro, trifluoromethyl, C1 to C4 alkyl or C1-C4 alkoxy radical; R1 represents a hydrogen atom or a hydroxy, alkyl, cycloalkyl, aryl, chloroaryl, aralkyl, alkylsulphonyl, arylsulphonyl or primary or secondary amino radical; and R2 represents a hydrogen atom or an acyl, alkyl, cycloalkyl, aralkyl, aryl, alkoxy, aryloxy, alkylmercapto, arylmercapto, or primary or secondary amino radical, are stated to be pest control agents which may be employed in admixture with solid or liquid, diluents or carriers.

    Abstract: Compounds of the general formula wherein X is oxygen or sulphur, aryl is a phenyl radical which may also be substituted with halogen or nitro groups, especially with chlorine groups, R1 is hydrogen, a lower alkyl or alkenyl radical or halogen-substituted lower alkyl radical or aryl group, R2 is hydrogen, lower alkyl, lower alkenyl or aryl, or halogen-substituted lower alkyl radicals and R2 may also be an alkylene radical linking the whole phosphoric or thio-phosphoric diaryl-ester-amide group to another same or different group of this type and R1 and R2, together with the nitrogen atom, may also form a saturated heterocyclic ring system, used as active ingredient in rodenticidal compositions (see Group VI) are prepared by amidation of phosphoric or thiophosphoric acid chlorides or by the conversion of amidophosphoric acid or amidothiophosphoric acid chlorides with the corresponding phenols or phenolates. In an Example the compound of the formula is prepared by reacting parachlorophenol dissolved in aqueous sodium hydroxide with dimethylamidophosphoric acid dichloride. In another example the compound of the formula is prepared by reacting O,O-di-para-chlorophenyl phosphoric acid ester monochloride with ammonium hydroxide. Many other compounds are given including ethylene-1,2,-diamido-N,N1-(bis - phosphoric or thio - phosphoric acids-4,41-dichloro-diphenyl ester). Several other products are specified.ALSO:A rodenticidal composition comprises as active ingredient, preferably in the proportion by weight of 0,05 to 1% a compound of the general formula wherein X is oxygen or sulphur, aryl is a phenyl radical which may also be substituted with halogen or nitro groups, especially with chlorine groups, R1 is hydrogen, a lower alkyl or alkenyl radical or halogen-substituted lower alkyl radical or aryl group, R2 is hydrogen, lower alkyl, lower alkenyl or aryl, or halogen-substituted lower alkyl radicals and R2 may also be an alkylene radical linking the whole phosphoric or thiophosphoric diaryl-ester-amide group to another, same or different group of this type and R1 and R2, together with the nitrogen atom, may also form a saturated heterocyclic ring system, the active ingredient being in an aqueous emulsion containing a suitable emulsifier. Many specified active ingredients are given.
