“…27 A lower melting point of 3,4-dinitropyrazole (3,4-DNP) 28 was achieved through a group transformation from 3,5-dinitropyrazole (3,5-DNP). 29,30 Similarly, better properties of compounds 3,3 0 -dinitramino-4,4 0 -bifurazane (DNABF) 30 and CL-20 31 were obtained through skeleton transformation from 5,5 0 -dinitramino-3,3 0 -bi(1,2,4-oxadiazole) (DNBO) 32 and 3,6-bis (2,2,2-trinitroethylnitramino)-1,2,4,5-tetrazine (BTAT), 33 respectively.…”
