Abstract:
In the title compound, [Ag(2)(C(5)H(2)N(2)O(4))(NH(3))(2)], each of the two Ag(I) atoms is coordinated by two N atoms from an ammonia mol-ecule and a 5-carb-oxy-1H-imidazole-4-carboxyl-ate ligand in an almost linear geometry, and by one carboxyl-ate O atom with a weak inter-action. The Ag atoms are assembled into a linear tetra-mer through Ag⋯Ag inter-actions. Each Ag tetra-mer is linked by four 5-carb-oxy-1H-imidazole-4-carboxyl-ate ligands, forming a puckered chain. The complex involves a strong intra-molecular O-H⋯O hydrogen bond.

Imines are formed under mildly acidic conditions. A pH of 4.5 is ideal for the reaction.
If the pH is low or the solution is too acidic, the reaction slows down in the...

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...
