The Perkin reaction gives an alpha, beta-unsaturated aromatic acid via the aldol condensation of an aromatic aldehyde and an acid anhydride. The alkali salt of the acid is also present. This alkali salt acts as a base catalyst .
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.
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.
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.

Jun 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.
6 days ago · Perkins’s condensation mechanism consists of five steps. The first step involves deprotonation using a weak base. The second step involves the formation of a carbanion.
Jul 27, 2022 · The Perkin reaction is a well-established organic reaction that produces α,β-unsaturated aromatic acids by condensing an aromatic aldehyde with an aliphatic acid anhydride in the presence of a weak base.
The Perkin reaction may be regarded essential as the condensation of a carbonyl component A and an acid and dihydride-salt combination B. The discussion here is a survey of the types of carbonyl components and acid anhydride salt combinations that can be used and of the yields obtained under favorable conditions.
