Question

What Is The Perkin Reaction In Carbonyl Compounds?

Answer 1

Perkin Reaction

• William Henry Perkin, an English chemist, discovered the Perkin Process, an organic chemical reaction. The unsaturated$\alpha ,\beta$aromatic acid is produced by this reaction.
• As part of the Perkin reaction mechanism, aromatic aldehydes, aliphatic acid anhydride, and the acid's alkali salt react to produce derivatives of cinnamic acid. The organic chemical reaction known as the Perkin reaction was first described by William Henry Perkin.

Perkin Reaction In Carbonyl Compounds

• Perkin developed a method for producing coumarin by heating the sodium salt of salicylaldehyde with acetic anhydride.
• The Perkin reaction was created as a result of further research into this reaction and is currently the standard method for producing cinnamic acid and its analogs.
• It is assumed that the Perkin reaction proceeds by converting the acid anhydride into an enolate anion, which then combines with the aldehyde to produce an alkoxide.
• The cinnamic acid ester is created by acylation and removal of the beta acyloxy derivative, which is made possible by the intramolecular acylation that is ensured. Cinnamic acid is produced by ester hydrolysis.
