An unexpected reaction of 1,5-diaminotetrazole: Novel preparation of 5-picrylamino-1,2,3,4-tetrazole (PAT)-highly insensitive energetic compound

摘要

This work reports on the preparation of 5-picrylamino-1,2,3,4-tetrazole (PAT) by an unexpected reaction of 1,5-diaminotetrazole (DAT) with picryl chloride (PiCl). The structure of PAT was confirmed by single-crystal X-ray diffraction. A suggested mechanism for its formation was presented. Some of the energetic properties of the synthesized compound were also studied. The results show that PAT is highly insensitive.
