SUBSTITUTED N-(1,2,4-TRIAZOL-3-YL)ARYLCARBOXAMIDE COMPOUNDS AND THEIR USE AS HERBICIDES

N-(1,2,4-triazol-3-yl)arylcarboxamides of formula (I) and their use as herbicides. The invention relates to N-(1,2,4-triazol-3-yl)arylcarboxamides of formula (I) and their use as herbicides. In said formula (I), X represents N or CR2, whereas R

Reaction of 4-Alkyl/arylthiosemicarbazides with Cyanamide

The condensation of cyanamide with 4-alkyl/arylthiosemicarbazide hydrochlorides (I.HCl) results in the formation of 2-alkyl/arylamino-5-amino-1,3,4,-thiadiazoles (III) and 3-amino-4-alkyl/aryl-5-mercapto-1,2,4-triazoles (IV).

Oxidation and Eliminative Cyclisation of S-Alkylisodithiobiureas

Isothiocyanates condense with S-alkylisothiosemicarbazides to yield S-alkylisodithiobiureas.These undergo cyclisation to give 3-amino-5-mercapto-4-substituted-1,2,4-triazoles with the elimination of alkyl mercaptan on heating under neutral conditions, whereas under acidic conditions, by elimination of ammonia 5-alkylmercapto-2-substituted amino-1,3,4-thiadiazoles are formed.Condensation of isothiocyanates with thiosemicarbazides in the presence of alkali affords 1-substituted dithiobiureas.Alkylation of these dithiobiureas with alkyl halides results in the formation of 5-alkylmercapto-2-substituted-amino-1,3,4-thiadiazoles, any intermediateproduct not being isolable.On the other hand, oxidation of 1-substituted dithiobiureas with either hydrogen peroxide or iodine furnishes 2-amino-5-substituted-amino-1,3,4-thiadiazoles.
