5, 6-Di(trinitroethylamino)furazano[3,4-b]pyrazine(DNFP) was synthesized from 5, 6-dihydroxyfura-zano[3,4-b]pyrazine by four steps reactions including chlorination, amination, N-hydroxymethyl and condensation reaction in a yield of 31%. And its structure was determined by IR, ¹H NMR, ¹³C NMR and elemental analysis. The reaction condition and mechanism of DNFP were studied. The heat of formation of DNFP was calculated by DFT/B3LYP methods, and other detonation performances of DNFP were predicted by Kamlet-Jacobs formula. Results show that its heat of detonation is 6714 J·g^-1, detonation velocity 8.91 km·s^-1, and detonation pressure 36 GPa.
