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.

∙ 9y agoThe Perkin reaction is sometimes called Perkin condensation. It was developed by the chemist, William Henry Perkin. It is a method used in organic chemistry to make cinnamic acids which are organic, crystalline compounds.

What is the mechanism of ferric chloride test?
reaction and meachanism of neutral feric chloride with phenols
What is the Reaction of iron sulphate with potassium iodide?
no reaction in aq solution, but if both powder used iodine will be generated with so2 releasing.......i am trying to work out the mechanism
What kind of reaction take place between the magnesium and EDTA?
Magnesium and EDTA react very quickly through a highly energized ionization reaction in which the EDTA can lose up to 4 hydrogens. The powerful ionization drives the reaction to completion. You can titrate the magnesium and calculate the point of reaction to better understand the mechanism
What would be the effect of carrying out the sodium iodide in acetone reaction with the alkyhalides using an iodide solution half as concentrated?
A reaction with alkyl halides in NaI with acetone is by the Sn2 mechanism. The rate for an Sn2 mechanism is directly proportional to the concentration of the nucleophile: rate = k[nucleophile][alkylhalide] If the iodine solution (the nucleophile) is half as concentrated, then the rate will also be halved. rate = k [nucleophile]/2 [alkyl halide]
Why is KI a catalyst for H202 decomposition but KBr and KCl aren't?
The mechanism of catalysis involves the I- ion only. The mechanism is: H2O2 + I- --> IO- + H2O H2O2 + IO- --> I- H2O O2 Second step regenerates the I- ion (thus acts as a catalyst). This reaction is first order wrt to both H2O2 and I-. Notably exothermic reaction. Must be in a medium which allows formation of I-, ie dissociation of KI. Water is a wonderful example.
What is the mechanism for the synthesis of E and Z alpha phenylcinnamic acid?
the perkin reaction
Why perkin reaction is not possible for aliphatic aldehyde?
In perkin reaction we take aliphatic aldehydes the base readily reacts with aipha hydrogen and give major of the aldol product.
How can reaction be classified?
mechanism. mechanism.
Is there any exceptional case of Perkin reaction?
yes synthesis of phenanthrene is an exceptional case of perkin reaction.here acetate ion is added to aromatic aldehydes though acetic anhydrides usually work it out
What has the author Gibson Dyson written?
Gibson Dyson has written: 'Perkin's reaction' -- subject(s): Accessible book
What is reaction mechanism of uric acid and ascorbic acid?
give structure of reaction mechanism of uric acid
What is the mechanism for the aldol condesation reaction of acetone and p-anisaldehyde?
Write a reaction mechanism for cinnamaldehyde and acetone
What is the mechanism of reaction between Wagner's reagent and alkaloids?
what is the reaction mechanism between wagner's reagent and alkaloids
What do we call each step that makes up a reaction mechanism?
Each step in a reaction mechanism is referred to as an elementary step.
Can a reaction mechanism be determined without an experiment?
A reaction mechanism can be proposed using computational studies. But needs to be experimentally proved.
When did Harold Perkin die?
Harold Perkin died in 2004.
When was Perkin Medal created?
Perkin Medal was created in 1906.
