azo compound

The last step is a photolysis of the azo compound.

It is the simplest example of an azo compound.

This method is used most often with organic peroxides or azo compounds.

Typical examples are halogen molecules, azo compounds, and organic peroxides.

It is a free radical-generating azo compound.

Because of their instability, aliphatic azo compounds pose the risk of explosion.

Radical initiators, especially azo compounds and organic peroxides, are inherently unstable.

Neutralized with a strong base, the azo compound (3) could be crystallized with 65% yield.

Addition reactions have employed imines, oximes, azides, azo compounds, and others.

Aryl azo compounds are usually stable, crystalline species.

Owing to this process, some aliphatic azo compounds are utilized as radical initiators.

Consequently, aromatic azo compounds tend to be brightly colored due to the extended conjugated systems.

When chiral oxazolidinones are used in conjunction with azo compounds, enantioselectivity is observed (see above).

Heating to 200 C extrudes sulfur in this compound and forms the corresponding azo compound.

Azobenzene is the prototypical aromatic azo compound.

The nucleophilic addition of the enolate anion 2 to the diazonium salt produces the azo compound 3.

As a consequence of п-delocalization, aryl azo compounds have vivid colors, especially reds, oranges, and yellows.

Aryldiazonium couple with electron-rich aromatic compounds such as a phenol to form azo compounds.

It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound.

Some azo compounds, e.g., methyl orange, are used as acid-base indicators due to the different colors of their acid and salt forms.

The resulting azo compounds are often useful dyes and in fact are called azo dyes.

It reacts with nitrous acid to form diazonium salt, which can undergo coupling reaction to form azo compound.

Homolysis can be brought about by heat or light but also by radical initiators such as organic peroxides or azo compounds.

Treatment of aromatic nitro compounds with metal hydrides gives good yields of azo compounds.

Azo pigments are colorless particles (typically earths or clays), which have been colored using an azo compound.
