摘要

Although energetic regioisomers have attracted intensive attention due to their interesting structure-property correlation, their effective synthesis and accurate identification has remained very difficult. In this paper, we synthesized two energetic regioisomers, namely 3-(4-aminofurazan-3-yl)-4-(4-nitrofurazan-3-yl)furoxan (ANFF-34) and 4-(4-aminofurazan-3-yl)-3-(4-nitrofurazan-3-yl)furoxan (ANFF-43),viaa controllable strategy with improved yields of 32% and 38%, respectively. The structures of ANFF-34 and ANFF-43 were unambiguously identified using comparative studies of(15)N NMR and single-crystal X-ray diffraction. Moreover, their thermal behaviours, and non-isothermal thermodynamic parameters were systematically investigated. Both ANFF-34 (T-m: 116.2 degrees C,T-d: 255.4 degrees C) and ANFF-43 (T-m: 106.2 degrees C,T-d: 255.6 degrees C) have similar thermal decomposition processes to that of DNTF. The superior performances of ANFF-34 (rho: 1.8 g cm(-3),D: 8214 m s(-1),P: 30.5 GPa, IS > 40 J) and ANFF-43 (rho: 1.7 g cm(-3),D: 7868 m s(-1),P: 27.0 GPa, IS > 40 J) indicate their great potential to be used as melt-cast carrier explosives. This study provides a solid foundation for the design and synthesis of new energetic compounds through isomer effects.
