▎ 摘  要

NOVELTY - A difurazan3,4-b;3',4'-b'piperazine2,3-e;5,6-e' bispyrazine penta-aza framework compound (I), is new. USE - New difurazan(3,4-b;3',4'-b')piperazine(2,3-e;5,6-e') bispyrazine penta-aza framework compound. ADVANTAGE - The ionic salts based on this framework compound exhibit excellent impact and friction sensitivity. DETAILED DESCRIPTION - A difurazan3,4-b;3',4'-b'piperazine2,3-e;5,6-e' bispyrazine penta-aza framework compound of formula (I), is new. An INDEPENDENT CLAIM is included for preparation of the compound (I), which involves (s1) dissolving a precursor 5,6-diaminofurazan3,4-b pyrazine of formula (II), in a solvent, cooling to 0-5℃ in an ice water bath, dripping tert-butyl hypochlorite of formula (III), into the solution, and reacting for 0.5-1 hour, (s2) raising the reaction solution to room temperature, adding an acid, stirring for 0.5-1 hour, and (s3) extracting the reaction solution with deionized water, taking an organic phase, and spin-drying.
