A new route to [1,2,4]triazolo[4,3-c][1,3,5,2]triazaphosphinine-5-oxides: reactivity of N-alkyl/aryl-n'-(4h-1,2,4-triazol-3-yl) amidines with N,N-dimethylphosphoramic dichloride

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. Bull. Chem. Soc.
