Abstract:
Heat-resistant energetic materials are critical for applications in extreme environments, such as aerospace vehicles and the exploitation of oil and gas resources. This study proposes an efficient C-N coupling strategy for facile construction of linked ring energetic materials with high thermal stability. Five new energetic materials (designated NPX-05 to NPX-09) exhibited outstanding thermal decomposition temperatures (Td: 342.7-390.3 °C) and high detonation velocity (D: 8163-8337 m s-1), demonstrating the effectiveness of the C-N coupling strategy for constructing novel heat-resistant energetic materials.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
