FERROCENYLAMINE

A general method for the preparation of ferrocenylamines involves the reactions of ferrocenyl bromide, FcBr*, with the sodium salt of an amine or amide in the presence of copper(I)bromide/pyridine.The syntheses of diferrocenylphenylamine and triferrocenylamine, NFc2Ph and NFc3, respectively, are reported, and the hydrolysis of N-ferrocenyl acetamide to give ferrocenylamine, NH2Fc, is described.The system of the ferrocenyl- and/or phenyl-substituted derivatives of ammonia, NFcnX3-n (n=0-3; X=H, Ph), is characterised on the basis of mass, UV VIS and in particular of 1H and 13C NMR spectroscopic data.

Acceptor-substituted ferrocenium salts as strong, single-electron oxidants: Synthesis, electrochemistry, theoretical investigations, and initial synthetic application

A series of mono- and 1,1′-diheteroatom-substituted ferrocene derivatives as well as acylated ferrocenes was prepared efficiently by a unified strategy that consists of selective mono- and 1,1′-dilithiation reactions and subsequent coupling with carbon, phosphorus, sulfur and halogen electrophiles. Chemical oxidation of the ferrocene derivatives by benzoquinone, 2,3-dichloro-5,6- dicyanobenzoquinone, AgPF6, or 2,2,6,6-tetramethyl-1-oxopiperidinium hexafluorophosphate provided the corresponding ferrocenium salts. The redox potentials of the synthesized ferrocenes were determined by cyclic voltammetry, and it was observed that all new ferrocenium salts have stronger oxidizing properties than standard ferrocenium hexafluorophosphate. An initial application of selected derivatives in an oxidative bicyclization revealed that they mediate the transformation under considerably milder conditions than ferrocenium hexafluorophosphate. Quantum chemical calculations of the reduction potentials of the substituted ferrocenium ions were carried out by using a standard thermodynamic cycle that involved the gas-phase energetics and solvation energies of the contributing species. A remarkable agreement between theory and experiment was found: the mean average deviation amounted to only 0.030-V and the maximum deviation to 0.1-V. This enabled the analysis of various physical contributions to the computed reduction potentials of these ferrocene derivatives, thereby providing insight into their electronic structure and physicochemical properties.

Synthesis, structure, and properties of 1,1?-diamino- and 1,1?-diazidoferrocene

We report an improved synthesis of 1,1?-diaminoferrocene, employing the reduction of 1,1?-diazidoferrocene with H2-Pd/C, along with extensive characterization data for both compounds. Diaminoferrocene undergoes a reversible 1e- oxidation in CH3CN at a potential of -602 mV vs Fc0/+, one of the most negative redox potentials for a ferrocene derivative. The chemical reversibility of this process was confirmed by isolation of the stable, 17-electron [Fc(NH2)2]+ cation as PF6-, OTf-, and TCNE- salts. In the solid state, diaminoferrocene exists in two conformations: one with the NH2 groups eclipsed, and the other with the NH2 groups offset by one-fifth turn around the Cp-Fe-Cp axis. Diazidoferrocene, on the other hand, exhibits only the fully eclipsed conformation in the solid state. The Fe-Cp(centroid) vectors in the diazidoferrocene molecules are roughly aligned with the crystallographic c-axis, and the molecules form layers perpendicular to this axis. The compound is thermally unstable at elevated temperatures, and rapid heating above its melting point results in explosion.
