Ultrasound assisted syntheses of some 1,2,4-triazole derivatives

A facile preparation of a series of 1,2,4-triazole derivatives under ultrasound irradiation, that proceeded via one-pot reaction of a- nitrophenyl hydrazones with different methylene amines, using sodium nitrite as oxidant and benzyl triethyl ammonium chloride (BTEAC) as phase transfer catalysis, respectively, was described.

Novel process for synthesis of 1,2,4-triazoles: Ytterbium triflate-catalyzed cyclization of hydrazonyl chlorides with nitriles

A series of 1,3,5-trisubstituted 1,2,4-triazoles were synthesized via the intermolecular cyclization of hydrazonyl chlorides with nitriles catalyzed by ytterbium triflate [Yb(OTf)3]. The amount of catalysis was discussed and Yb(OTf)3 could be reused without loss of activity. Copyright Taylor & Francis, Inc.

An improved synthesis of 1,2,4-triazoles using Ag2CO3

An improved synthesis of 1,3,5-trisubstituted 1,2,4-triazoles via Ag2CO3 mediated cyclization of triazenes has been developed. This approach is flexible and compatible with a wide range of functional groups. The reaction was complete within 3 h and the products were isolated in moderate to high yields. The influence of the β-substituents of the amines on the triazole formation was also studied. (C) 2000 Elsevier Science Ltd.

An approach to 1-aryl-1,2,4-triazoles

A series of different 1,3,5-trisubstituted 1,2,4-triazoles 9 have been readily prepared by simple oxidation of corresponding N-alkylamide arylhydrazones (amidrazones) 5 with hydrogen peroxide or potassium permanganate.

REACTION OF BENZONITRILE N-(p-NITROPHENYL)IMIDE WITH 5-SUBSTITUTED TETRAZOLES: A NEW ROUTE TO SUBSTITUTED 1,2,4-TRIAZOLES VIA N-HYDRAZONOYLTETRAZOLES

A wide range of phenyl 5-R-substituted (R = aryl, alkyl, amino, halo, H) 1- and 2-hydrazonoyltetrazoles has been synthesized.Substituent effects on the orientation of nitrile imide attack on 5-aryltetrazoles are reported.Thermolysis and fragmentation of t
