Structures of three kinds of amides: an organic amide (carboxamide), a sulfonamide, and a phosphoramide. In chemistry, the term amide (/ ˈ æ m aɪ d / or / ˈ æ m ɪ d / or / ˈ eɪ m aɪ d /) [1] [2] [3] is a compound with the functional group R n E(=O) x NR 2, where x is not zero, E is some element, and each R represents an organic group or hydrogen.

In organic chemistry, an amide, [1] [2] [3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C(=O)−NR′R″, where R, R', and R″ represent any group, typically organyl groups or hydrogen atoms.
Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −. Amido complexes of the parent amido ligand NH 2 − are rare compared to complexes with diorganylamido ligand, such as dimethylamido. Amide ligands have two electron pairs available for bonding.
Amides are the members of a group of organic chemical compounds containing nitrogen. 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 .
These reactions proceed via the intermediacy of amides. The intramolecular reaction of a carboxylic acid with an amide is far faster than the intermolecular reaction, which is rarely observed. They may also be produced via the oxidation of amides, particularly when starting from lactams. [6] R(CO)NHCH 2 R' + 2 [O] → R(CO)N(CO)R' + H 2 O
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. The anion NH − 2 is the conjugate base of ammonia, so it is formed by the self-ionization ...
The Einhorn–Brunner reaction is the designation for the chemical reaction of imides with alkyl hydrazines to form an isomeric mixture of 1,2,4-triazoles.It was initially described by the German chemist Alfred Einhorn in a paper, published in 1905, describing N-methylol compounds of amides. [1]
Transamidation is a chemical reaction in which an amide reacts with an amine to generate a new amide: RC(O)NR' 2 + HNR" 2 → RC(O)NR" 2 + HNR' 2. The reaction is typically very slow, but it can be accelerated with Lewis acid [1] and organometallic catalysts. [2] Primary amides (RC(O)NH 2) are more amenable to this reaction.
