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.
