A Synthetic Strategy for the Preparation of Fused [5,6,5,5]-Tetracyclic Energetic Compounds

This study explores a straightforward synthetic strategy for preparing fused [5,6,5,5]-tetracyclic energetic compounds. Compound 4 has a high thermostability (T-d = 307 degrees C), which is comparable to that of traditional heat-resistant explosive HNS (T-d = 318 degrees C), but a higher detonation velocity (8262 m s(-1)) than HNS (7612 m s(-1)). These results indicate that compound 4 deserves further investigation as a potential heat-resistant explosive.
