Iodine-Mediated Condensation–Cyclization of α-Azido Ketones with p-Toluenesulfonyl Hydrazide for Synthesis of 4-Aryl-NH-1,2,3-Triazoles

A molecular iodine mediated condensation–cyclization reaction for the synthesis of 4-aryl-NH-1,2,3-triazoles has been developed from readily available α-azido acetophenones and p-toluenesulfonyl hydrazide. This reaction provides a metal-free strategy for the sequential formation of C–N and N–N bonds in mild condition.

A method for the synthesis of the compounds 1, 2, 3 - triazole

The invention belongs to the technical field of preparation of pharmaceutical and chemical intermediates and particularly relates to a method for synthesizing a 1, 2, 3-triazole compound. The 1, 2, 3-triazole compound has substituents at 4th and 5th sites. The method comprises that a vicinal diol compound and a hydrazine derivative undergo a condensation reaction under oxidation of an oxidizing agent to produce an intermediate, and the intermediate and ammonia gas undergo a cyclization reaction after condensation under oxidation of an oxidizing agent to produce the 1, 2, 3-triazole compound with substituents at 4th and 5th sites. The method has high reaction specificity, safety and treatment convenience, belongs to the environment-friendly reaction type, needs mild post-treatment conditions, realizes oxidizing agent recovery and reuse, has simple processes and a high reaction yield, produces high quality products and is suitable for industrial production.

Thermal characterization of the solid state and raw material fluconazole by thermal analysis and pyrolysis coupled to GC/MS

This article had studied the thermal characterization of the raw material and different fluconazole crystals, obtained through recrystallization with different solvents using thermoanalytical techniques (TG, DTA, DSC-50, DSC Photovisual, DSC-60) and Pyr-GC/MS. The results confirmed that the fluconazole volatilizes without decomposition until 250 °C. Pyr-GC/MS showed hexachlorobenzene like impurities in fluconazole raw material.

β-Tosylethylazide (TSE-N3), which can be prepared in one step from p-tolyl vinyl sulfone and sodium azide/H2SO4, undergoes metal-catalyzed 1,3-dipolar cycloadditions with alkynes to produce TSE-protected 1,2,3-triazoles. T

Pyrolysis and Photolysis of 1-Aroylamino-4,5-diaryl-1,2,3-triazoles: Generation and Thermal Transformations of 4,5-Diaryl-1,2,3-triazolyl Radicals

The pyrolysis of 1-aroylamino-4,5-diphenyl-1,2,3-triazoles 1 yields, pressumably via the 4,5-diphenyl-1,2,3-triazolyl radical (2a), 2,3-diphenyl-2H-azirine (11a) and 2-aryl-4,5-diphenylimidazoles 14 as the major products. Upon irradiation 1-benzoylamino-4,5-diphenyl-1,2,3-triazole (1a) gives 4,5-diphenyl-1(2)H-1,2,3-triazole (4a) via the 1,2,3-triazolyI radical 2a, together with benzamide (5a) and 1,2-bisbenzoylhydrazine (6a). Products 5a and 6a result from the benzoylamino radical 3a by hydrogen atom abstraction and dimerization respectively.
