Abstract: Aromatic 7-R1-8-R2-3-tert-butylpyrazolo[5,1-c][1,2,4]triazines (R1 = H, Br; R2 = H, Me, Br) reacted with lithium diphenyl- and methyl(phenyl)phosphides in THF at lower temperature to give nucleophilic addition products to the C4 atom. Further oxidation with atmospheric oxygen or N-bromosuccinimide afforded previously unknown (3-tert-butylpyrazolo[5,1-c][1,2,4]triazin-4-yl)phosphine oxides and 2,2-dibromoacetamide as a by-product. The structure of the isolated compounds was confirmed by IR, 1H, 13C, and 31P NMR, and mass spectra and X-ray analysis.

The tris-dimorpholinomethyl-s-triazine 2 behaves as a synthetic equivalent of the still unknown triformyl-s-triazine 1.Thus from 2 we were able to prepare some characteristic derivatives 5 of the trialdehyde 1, triphenylhydrazones, trialdoxime, trisemicar
