Фенилдиазен

Description

Phenyldiazene (phenyldiimide) is a monoaryldiazene with the composition C₆H₅N=NH. The compound belongs to diazenes: the fragment –N=N– carries a phenyl group at one nitrogen, and a hydrogen at the other. It is an unstable substance that exists as a reaction intermediate and is not released as a stable commercial product under normal conditions.

Stability and decomposition products

Phenyldiazene is easily decomposed. Among the decomposition products are benzene as the corresponding hydrocarbon, molecular nitrogen, hydrazine, mono- and disubstituted hydrazines, azobenzene. Stability increases sharply with coordination on a transition metal: complexes of substituted diazenes are synthesized purposefully, and it is they that allow working with this fragment preparatively.

Scope of application

• synthetic intermediate in organic chemistry: reactivity and tendency to decompose are used in targeted transformations
• object of coordination chemistry - ligand in transition metal complexes, where the diazene fragment is stabilized
