Amide
Acid amide (amide) is a class of compounds, particularly organic compounds, and refers to those having a structure in which an oxo acid and ammonia or a primary or secondary amine are dehydrated and condensed. For example, the carboxylic acid amide has a structure of R - C (═O) - NR 1 R 2. Unless otherwise specified, in the case of simply "amide", it often refers to carboxylic acid amide. In addition, sulfonamide, phosphoric acid amide and the like are known. Normally, a carboxylic acid amide (R - C (═O) - NR 1 R 2) is formed by a dehydration condensation reaction between an amine and a carboxylic acid. Among the structures, the bond between the carbonyl group and nitrogen is particularly called an amide bond (the bond of the metal amide is not called an amide bond). ...
