Nitroalkynes: A Unique Class of Energetic Materials

Abstract

Forty-five years after their first preparation, nitroalkynes retain interest for their unique chemical behavior and their potential as energetic materials. This review encompasses the physical and spectral properties, synthesis, reactivity, metal complexes, and theoretical studies of nitroalkynes not previously reviewed, and those prepared after 1973. 1 Introduction 2 Physical Properties of Nitroalkynes 3 Spectral Properties of Nitroalkynes 4 Syntheses of Nitroalkynes 4.1 Unsuccessful Attempts 4.1.1 Nitration 4.1.2 Elimination 4.1.3 Retrocycloaddition 4.2 Successful Strategies 4.2.1 Nitration 4.2.2 Elimination 4.2.3 Nucleophilic Displacement 4.2.4 From Triazoles 4.3 Attempts at the Synthesis of Dinitroacetylene 5 Reactions of Nitroalkynes 5.1 Thermal Decomposition 5.2 Nucleophilic Addition 5.3 Cycloaddition 6 Metal Complexes 7 Theoretical Studies 8 Conclusion
