Abstract:
Iron carbonyl-stabilized cations have been employed to develop methodology for carbon-carbon and carbon-heteroatom formation suitable for the preparation of combinatorial libraries. Different nucleophiles were added to tricarbonyl(cyclohexa-1,3-dienylcarboxylic acid 4-nitro-phenyl ester)iron hexafluorophosphate. Aminolysis, followed by decomplexation, yielded substituted cyclohexadienyl amides of high purity. Carbon, oxygen, and sulfur nucleophiles gave good results, while amine nucleophiles gave products of somewhat lower purity.

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...

Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
