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.
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). IUPAC recommends ethanamide, but this and related formal names are rarely ...
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
Tetrakis(dimethylamino)titanium (TDMAT), also known as Titanium(IV) dimethylamide, is a chemical compound.The compound is generally classified as a metalorganic species, meaning that its properties are strongly influenced by the organic ligands but the compound lacks metal-carbon bonds.
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.

Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, and lipid modulator. [2] A main target of PEA is proposed to be the peroxisome proliferator-activated receptor alpha (PPAR-α). [3] [4] PEA also has affinity to cannabinoid-like G-coupled receptors GPR55 and GPR119. [5]
N-acyl amides are a general class of endogenous fatty acid compounds characterized by a fatty acyl group linked to a primary amine metabolite by an amide bond. Broadly speaking, N-acyl amides fall into several categories: amino acid conjugates (e.g., N-arachidonoyl-glycine), neurotransmitter conjugates (e.g., N-arachidonoyl-serotonin), ethanolamine conjugates (e.g., anandamide), and taurine ...
The amide link is produced from an amine group (alternatively known as an amino group), and a carboxylic acid group. The hydroxyl from the carboxylic acid combines with a hydrogen from the amine, and gives rise to water, the elimination byproduct that is the namesake of the reaction.
