Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2. It is a salt composed of the sodium cation and the azanide anion. This solid, which is dangerously reactive toward water, is white, but commercial samples are typically gray due to the presence of small quantities of ...
Sodium amide (also known as sodamide) is synthesized from sodium metal and ammonia with ferric nitrate catalyst. [3] [4] The sodium compound is white, but the presence of metallic iron turns the commercial material gray. 2 Na + 2 NH 3 → 2 NaNH 2 + H 2. Lithium diisopropylamide is a popular non-nucleophilic base used in organic synthesis.
The alkali metal derivatives are best known, although usually referred to as alkali metal amides. Examples include lithium amide, sodium amide, and potassium amide.These salt-like solids are produced by treating liquid ammonia with strong bases or directly with the alkali metals (blue liquid ammonia solutions due to the solvated electron): [1] [2] [4]
Examples of important inorganic sodium salts are sodium fluoride, sodium chloride, sodium bromide, sodium iodide, sodium sulfate, sodium bicarbonate and sodium carbonate. Sodium amide (NaNH 2) is the sodium salt of ammonia (NH 3).
Other strong non-nucleophilic bases are sodium hydride and potassium hydride. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions.
Sodium hydride: a strong base used in organic synthesis Sodium hydroxide: strong base with many industrial uses; in the laboratory, used with acids to produce the corresponding salt, also used as an electrolyte: Sodium hypochlorite: frequently used as a disinfectant or a bleaching agent Sodium nitrite: used to convert amines into diazo ...
Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of ...
Sodium azide is prepared by the reaction of sodium amide with nitrous oxide. This route is known as the "Wislicenus process": 2 NaNH 2 + N 2 O → NaN 3 + NaOH + NH 3. Hundreds of tons of azides are prepared in this way annually. [6] KN 3 is prepared by treating potassium carbonate with hydrazoic acid.
