Abstract:
In the solid state, 4-methoxy-N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C(10)H(10)Cl(3)N(3)O, (I), N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C(9)H(8)Cl(3)N(3), (II), 4-chloro-N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C(9)H(7)Cl(4)N(3), (III), 4-bromo-N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C(9)H(7)BrCl(3)N(3), (IV), and 4-trifluoromethyl-N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C(10)H(7)Cl(3)F(3)N(3), (V), display strong intramolecular N-H...N hydrogen bonding across the chelate ring and also intramolecular N-H...Cl contacts. Additional intermolecular hydrogen bonds link the molecules into chains, double chains or sheets in all cases except for compound (V). For compound (II), there are three independent molecules per asymmetric unit.

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.
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
