Sodium hydride Uses

Sodium hydride (CAS NO.7646-69-7) is primarily used as a strong base in the organic synthesis.It is a base of wide scope and utility in the organic chemistry. It has the main uses as follows:
1.capable of deprotonating a range of even weak Bronsted acids to give the corresponding sodium derivatives. The resulting sodium derivatives can be alkylated.
2.Sodium hydride is most notably employed to deprotonate carbon acids such as 1,3-dicarbonyls and analogues such as malonic esters.
3.It is widely used to promote condensation reactions of carbonyl compounds via the Dieckmann condensation, Stobbe condensation, Darzens condensation, and Claisen condensation.
4.Sodium hydride is also used to make sulfur ylides, which in turn are used to convert ketones into epoxides.Sodium hydride reduces certain main group compounds, but the analogous reactivity is unknown in the organic chemistry.
5.Because of its rapid and irreversible reaction with water, Sodium hydride can be used to dry some organic solvents.
