BENZOIN FOR SYNTHESIS, BENZOIN
Benzoin for synthesize, by using the sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate and other cheap strong alkali weak acid salts as alkaline reagents, the benzaldehyde is subjected to benzoic condensation reaction under the catalytic action of the VB1 to synthesize the benzoin.
The main uses of benzoin are as a precursor to benzil, which is a photoinitiator The conversion proceeds by organic oxidation using copper(II), nitric acid, or oxone.
Benzoin can be used in the preparation of several pharmaceutical drugs including oxaprozin, ditazole, and phenytoin.

The reaction is helpful in the synthesis of heterocyclic compounds and also extends to the aliphatic form of aldehydes.
Benzoin Condensation is a coupling reaction between two aldehydes that allows the preparation of α-hydroxyketones
