fischer esterification method
What is the Fischer esterification mechanism?
Thus, the required ester is produced. The Fischer esterification Mechanism can simply be described as – Protonation of the carbonyl, followed by the nucleophilic attack on the carbonyl, the proton transfer to the OH group, the removal of water and finally the deprotonation step.
Are Fischer esterification routes mutually exclusive with acetic anhydride routes?
However, in many carefully designed syntheses, reagents can be designed such that acid anhydrides are generated in situ and carboxylic acid byproducts are reactivated, and Fischer esterification routes are not necessarily mutually exclusive with acetic anhydride routes.
What is esterification in chemistry?
Esterification is the reaction of an acid (acid carboxyl group condensation) in the presence of a catalyst with alcohol (alcohol hydroxyl group). Put your understanding of this concept to test by answering a few MCQs. Click ‘Start Quiz’ to begin!
