Title (EN) PRODUCTION OF 1,2,3-TRIAZOLES BY CYCLOCONDENSATION OF HYDRAZIDES WITH GLYOXAL AND AMINES
(FR) PRODUCTION DE 1,2,3-TRIAZOLES PAR CYCLOCONDENSATION D'HYDRAZIDES AVEC DU GLYOXAL ET DES AMINES
Abstract: front page image
(EN)1H-1,2,3-triazole and its N?1¿-aryl or N?1¿-alkyl derivatives are obtained by reaction of a hydrazide RNHNH¿2?, wherein R is acyl or sulfonyl, with glyoxal followed by treatment of the intermediate hydrazone RNHN=CHCHO, which does not require isolation, with ammonia or an appropriate amine.
(FR)Du 1H-1,2,3-triazole et ses dérivés N?1¿-aryle ou N?1¿-alkyle sont obtenus par réaction d'un hydrazide RNHNH¿2?, où R représente acyle ou sulfonyle, avec du glyoxal, ladite réaction étant suivie du traitement de l'hydrazone intermédiaire RNHN=CHCHO, qui ne nécessite pas une isolation, avec de l'ammoniac ou une amine appropriée.
