Molecular Formula: NaH
Molecular Weight: 24.00
Product description:Sodium hydride is in the organic synthesis USES a wide range of alkali (pKa ~ 36). It can take many compounds (even weak Br? nsted acid) of the proton and generate the corresponding sodium compounds. Typical examples are: alcohol, phenol, pyrazole, mercaptan, etc. Sodium hydride are most often used in 1, 3 - dicarbonyl compounds, maleic acid ester and similar compounds to proton, corresponding sodium compounds can be alkylation, so as to be able to generate a variety of organic compounds. Corresponding see Dieckmann condensation reaction, Stobbe condensation reaction, Darzens condensation reaction and Claisen condensation reaction. Dimethyl sulfoxide is a common solvent. Sodium hydride is also used to synthesis of sulfur ylide, so as to realize the transformation of ketone to epoxy compound. Sodium hydride synthesis dithioimidodiphosphinate can, this is acetylacetone complexes in the areas of concern.
