Azo Radical (Noun)
Meaning
The bivalent group -N=N- united to two hydrocarbon groups.
Classification
Nouns denoting substances.
Examples
- Azo-radicals have been isolated as relatively stable molecules when the attached groups are very large and prevent further reaction.
- Azo-radicals react as biradicals with cyclohexadiene, with carbon-centered radicals and with alkenes to form carbon-nitrogen bonds.
- Cyclophanes, or intramolecular coupled compounds, may result when an azo-radical abstracts hydrogen from its other group to couple internally.
- Many types of organic azo-radicals are prepared from tetrazolium salts in one-electron reduction steps with cyanide.
- Univalent groups formed from cleavage of a 2-tetrazolium ring also undergo addition with radicals as an azo-radical, whereupon this one radical continues further in other pathways.
