4-Amino-5-(2-hydroxy-benzyl-idene-amino)benzene-1,2-dicarbonitrile
1Department of Pharmacy, Mudanjiang Medical University, Mudanjiang, 157011, People's Republic of China.
Abstract:
A new tetra-dentate unsymmetrical Schiff base, C(15)H(10)N(4)O, has been synthesized from 4,5-dicyano-o-phenyl-enediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°. There are intra-molecular O-H⋯N and weak inter-molecular N-H⋯O and N-H⋯N inter-actions.

Nomenclature 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.
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
Structures of Carboxylic Acid Derivatives
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 unhybridized p...
