- 4-(1-Imidazolium) butane sulfonate is an excellent catalyst for the synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles through the condensation of 1,2-dicarbonyl compounds, aldehydes, and ammonium ...
- Multinuclear NMR Characterization of Cyanuric Fluoride (2,4,6-Trifluoro-1,3,5-triazine)

- Although 2,4,6-trifluoro-1,3,5-triazine, C3F3N3, is a highly symmetrical molecule, its NMR parameters can be obtained by reducing its symmetry through the introduction of N-14/N-15 and C-12/C-13 isotopomers. Experimental...
- Synthesis of Monosubstituted 1,3,4-Selenadiazoles Using Woollins' Reagent
[作者:OSTROWSKI WOJCIECH; GIERCZYK BLAZEJ; FRANSKI RAFAL,期刊:Journal of Heterocyclic Chemistry, 页码:1266-1268 , 文章类型: Article,,卷期:2012年49-5]
- New series of 1,3,4-selenadiazoles was obtained. The method of synthesis employs the Woollins' reagent and N,N'-diacylhydrazides. Reaction in toluene leads to monosubstituted 1,3,4-selenadiazoles with a yield 26-57%.
