Abstract:
The title compound, C(16)H(10)N(2)O(8)·2C(3)H(7)NO, was synthesized by the reductive condensation reaction of 5-nitro-isophthalic acid in the presence of NaOH. The tetra-acid mol-ecule, which has a crystallographically imposed centre of symmetry, adopts an E configuration with respect to the azo group. In the crystal packing, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen-bonding inter-actions, forming chains propagating in [20].

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...
