Abstract
A series of novel [1,2,4]triazolo[4,3-c][1,3,5,2]triazaphosphinine-5-oxidederivatives 2a-h were synthesized by a reaction of N-alkyl/aryl-N'-(4H-1,2,4-triazol-3-yl) amidines with N,N-dimethylphosphoramic dichloride in the presence of triethylamine (TEA) in refluxing 1,4-dioxane. The structures of all the synthesized compounds have been established by NMR (1H, 13C, 31P) and IR spectroscopy, as well as by elemental analysis and mass spectral analysis.
