The Perkin reaction is an organic reaction developed by English chemist William Henry Perkin that is used to make cinnamic acids. It gives an α,β-unsaturated aromatic acid or α-substituted β-aryl acrylic acid by the aldol condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid.
Perkin’s reaction mechanism includes the reaction between aromatic aldehydes, the aliphatic acid anhydride, and the alkali salt of the acid to give cinnamic acid derivatives. The Perkin reaction is an organic chemical reaction named after its discoverer – William Henry Perkin.
The Perkin reaction, also known as Perkin condensation, is an organic reaction which is used for the synthesis of α,β-unsaturated aromatic acid by the condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid acting as a weak base.
Jan 28, 2022 · Perkin condensation reaction is the condensation reaction of an aromatic aldehyde and an aliphatic acid anhydride containing at least two α-hydrogen atoms in the presence of a sodium or potassium salt of the corresponding acid to form, α, β-unsaturated acid.
Jan 23, 2023 · The Perkin reaction is an organic reaction developed by William Henry Perkin that is used to make cinnamic acids. It gives an α,β-unsaturated aromatic acid by the aldol condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid.
Jul 15, 2024 · The Perkin reaction (or Perkin condensation) is an condensation of aromatic aldehydes and the anhydrides of aliphatic carboxylic acids in the presence of a weak base to obtain α,β-unsaturated carboxylic acids.
Aug 24, 2023 · The Perkin condensation reaction, also known as the Perkin reaction, is an organic reaction used to produce, unsaturated aromatic acid via condensation of an aromatic aldehyde and an acid anhydride in the presence of an alkali salt of the acid serving as a weak base.
Jul 18, 2024 · Perkin’s reaction is an organic reaction proposed by William Henry Perkin, an English Chemist, in the year 1868. The reaction belongs to the Carbonyl compounds and is used to make ɑ-, and β-unsaturated aromatic acids. Perkin used this reaction to make cinnamic acids.
In 1868, W. H. Perkin described a synthesis of coumarin by heating the sodium salt of salicyaldehyde with acetic acid. Further study led to a new discovery for preparing cinnamic acid and its analogs by means of a synthesis of very general application, which became know as the Perkin reaction.
Perkin reactions produce cinnamic acids, a form of naturally occurring carboxylic acid, through heating and aldehyde and dehydration. Learn the mechanism, application, and uses of the Perkin...
