In “Organic Preparation based on some name reactions”, I discuss some laboratory methods for preparation of some organic compounds based on name reaction like, Claisen-Schmidt Reaction, Beckmann Rearrangement, Diels-Alder Reaction, Pechmann Condensation, Fischer Indole Synthesis, Haloform Reaction, Knorr Quinoline Synthesis, Kolbe - Schmitt Reaction, etc.
In the last chapter there is a discussion about Purification of organic compounds and their various methods.

What are "Named Reactions" in organic chemistry?
Named reactions are chemical reactions named after their discoverers, such as the Diels-Alder or Cannizzaro reaction. They are fundamental building blocks in organic synthesis.
How can Benzyl alcohol and Benzoic acid be prepared?
They can be synthesized from Benzaldehyde using the Cannizzaro Reaction, which involves the base-induced disproportionation of non-enolizable aldehydes.
What is the Diels-Alder Reaction used for?
It is used to synthesize cyclic compounds, such as 9,10-dihydroanthracene-a,ß-succinic anhydride from Anthracene, by reacting a conjugated diene with a dienophile.
Why is the purification of organic compounds important?
Purification is essential to remove side products and unreacted starting materials. Methods include distillation, solvent extraction, and recrystallization.
What is the Fischer Indole Synthesis?
It is a method to prepare indole derivatives, such as 1,2,3,4-Tetrahydrocarbazole, from cyclohexanone and phenylhydrazine under acidic conditions.
