Abstract:
The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding inter-actions, principally O-H⋯O inter-actions between all three species in the asymmetric unit. An R (2) 4(8) graph-set hydrogen-bonding motif between the anion and water mol-ecules serves as a unit which links to the cation via the di-ethano-lamine group. Each O atom of the acetate anion accepts two hydrogen bonds.

Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
01:11Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.

The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
01:28Amides to Carboxylic Acids: Hydrolysis
Acid-catalyzed hydrolysis:
Hydrolysis of amides under acidic conditions yields carboxylic acids. Since the reaction occurs slowly, hydrolysis requires the conditions of heat.
The mechanism begins with the protonation of the carbonyl oxygen by the acid catalyst. The protonation makes the amide carbonyl carbon more...
