Formyl Azide: Properties and Solid-State Structure

摘要

Covalent azides are important reagents in chemistry, biology, medicine, and materials science. Owing to the explosive nature of this class of compounds, some simple azides had not been isolated as neat substances, although they have been known to exist for a long time, and it took several decades to fully disclose their structures and properties. For instance, the solid-state structure of the simplest covalent azide, HN3, which was first synthesized by Curtius in 1890, has only very recently been reported by Klapotke et al. The same is true for the simple halogen azides C1N3, BrN3, and IN3, while the molecular structure of highly explosive FN3 is up to now only available from a gas-phase microwave study.
