The core −C(=O)−(N) of amides is called the amide group (specifically, carboxamide group). In the usual nomenclature, one adds the term "amide" to the stem of the parent acid's name. For instance, the amide derived from acetic acid is named acetamide (CH 3 CONH 2 ).
The term amide may also refer to amide group, a functional group –C(=O)N= consisting of a carbonyl adjacent to a nitrogen atom. cyclic amide or lactam, a cyclic compound with the amide group –C(=O)N– in the ring. metal amide, an ionic compound ("salt") with the azanide anion H 2 N − (the conjugate base of ammonia) or to a derivative ...
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 ...
Specifically, an amide results from an acid, in which a carbon atom is double bonded to oxygen and also to a hydroxyl group, when the hydroxyl group is replaced by an amine. Subcategories This category has the following 13 subcategories, out of 13 total.
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 resulting nitrilium ion is hydrolyzed to the desired amide. Primary, [7] secondary, [4] tertiary, [8] and benzylic [9] alcohols, [1] as well as tert-butyl acetate, [10] also successfully react with nitriles in the presence of strong acids to form amides via the Ritter reaction. A wide range of nitriles can be used.
This amide has two amino groups (– NH 2) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. [6] Urea serves an important role in the cellular metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.
Azanide is the IUPAC-sanctioned name for the anion NH − 2.The term is obscure; derivatives of NH − 2 are almost invariably referred to as amides, [1] [2] [3] despite the fact that amide also refers to the organic functional group – C(=O)−NR 2.
