Abstract:
The mol-ecule of the title compound, C(24)H(20)N(2)O(2), lies on a twofold rotation axis that relates one 2-(N-methyl-formamido)-naphthyl unit to the other. The N-methyl-formamido substituent is twisted by 54.9 (1)° with respect to the naphthalene fused-ring system; the two fused-ring systems are themselves twisted by 70.3 (1)°.

01:17Nomenclature of Primary Amines
Primary, secondary, and tertiary amines are compounds consisting of one, two, and three alkyl groups connected to the amino group (–NH2), respectively. As depicted in Figure 1, the common name of the primary amines is obtained by adding the suffix -amine to the alkyl substituent attached to the amino group as the corresponding alkylamine.
01:11Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
Naming Amides
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.
