What is Fischer esterification?
1) Protonation of the carbonyl by the acid. The carbonyl is now activated toward nucleophilic attack. Fischer esterification is the esterification of a Carboxylic acid by heating it with an alcohol in the presence of a strong acid as the catalyst.
What is Fischer esterification radical site rearrangement (McLafferty rearrangement)?
Fischer Esterification Radical Site Rearrangements (McLafferty Rearrangement). Carbonyl derivatives readily undergo a rearrangement reaction in which the M undergoes intramolecular H atom transfer to the carbonyl oxygen atom.
