Why perkin reaction is not possible for aliphatic aldehyde?
The Perkin reaction typically involves the condensation of aromatic aldehydes with an acid anhydride in the presence of a base to form an α,β-unsaturated carboxylic acid. Aliphatic aldehydes lack the necessary stabilization of the intermediate enolate ion due to the absence of conjugation with an aromatic ring, making the Perkin reaction unfavorable for aliphatic aldehydes.
William Henry perkin their contribution to chemistry?
William Henry Perkin is best known for his accidental discovery of the first synthetic organic dye, called mauveine or mauve. This discovery revolutionized the dye industry and paved the way for the creation of other synthetic dyes, leading to the birth of the chemical industry. Perkin's work laid the foundation for the field of synthetic organic chemistry and had a significant impact on the textile industry.

What is the mechanism for perkin reaction?
Start with the aromatic aldehyde and acid anhydride. Salt of an Carboxylic acid is used to abstract a proton from the alpha carbon of acid anhydride. The carbanion generated would attack the electrophillic centre of aldehyde. This centre is carbonyl carbon. There after an stablised anion is formed. Further hydrolysis gives the required Cinnamic acid.
