2,4,6,8-Tetraazidopyrimido[5,4-]pyrimidine: a novel energetic binary compound

Quadruple azidation of 2,4,6,8-tetrachloropyrimido[5,4- d ]pyrimidine gave tetraazidopyrimido[5,4- d ]pyrimidine (C 6 N 16 ) with 86% yield. The title compound undergoes azide-tetrazole tautomerism in neutral organic solvents, but exists as a protonated C 2 -symmetric tetraazide dication in trifluor...

Zusammenfassung:Quadruple azidation of 2,4,6,8-tetrachloropyrimido[5,4- d ]pyrimidine gave tetraazidopyrimido[5,4- d ]pyrimidine (C 6 N 16 ) with 86% yield. The title compound undergoes azide-tetrazole tautomerism in neutral organic solvents, but exists as a protonated C 2 -symmetric tetraazide dication in trifluoroacetic acid. On the other hand, in the solid state it occurs as a monotetrazole tautomer as revealed by its single crystal X-ray analysis. The newly obtained binary compound C 6 N 16 is very sensitive towards both impact (
