Three series of ruthenium complexes with the general formula Ru(bpy)n(β-diketonato)3−n (bpy = 2,2’bipyridine, n = 0, 1, 2) were prepared and investigated using cyclic voltammetry and UV-vis spectroscopy. Variation of both the number and electronic demand of the β-diketonato ligands resulted in well-defined modulation of the potential at which oxidation of the metal centre occurred. The observed...

The asymmetric unit of the title compound, [Fe(C5H5)(C5H4BrHg)], contains two independent mol-ecules, A and B, in which the Hg-C bond lengths are 2.045 (6) and 2.046 (6) Å, the Hg-Br bond lengths are 2.4511 (9) and 2.4562 (7) Å, and the C-Hg-Br angles are 176.42 (17) and 177.32 (17)°. The two cyclo-penta-dienyl rings of mol-ecule A are eclipsed, while those of mol-ecule B are almost staggered. ...

In the title mol-ecule, [Fe(C(5)H(5))(C(16)H(12)N)], the cyclo-penta-dienyl rings are approximately eclipsed and the inter-planar angle is 0.8 (7)°. The Fe atom is slightly closer to the substituted cyclo-penta-dienyl ring, with an Fe⋯centroid distance of 1.639 (2) Å, compared with 1.645 (2) Å for the unsubstituted ring. The C=N double bond is essentially coplanar with the substituted cyclo-pen...

Our electrochemical cell consisted of a ferrocene-included hemispherical nitrobenzene (NB) droplet on the glassy carbon (GC) electrode which was immersed in the aqueous solution including sodium sulfate and sodium dodecyl sulfate (SDS). When an air bubble was injected near the boundary between the oil and the aqueous phase, it stayed at the top of the hemisphere on the boundary so that the lowe...

1-(N,N-Dimethylaminomethyl)-1'-(diphenylphosphanyl)ferrocene (1) was synthesized in good yield by lithiation of 1-bromo-1'-(diphenylphosphanyl)ferrocene and subsequent reaction with Eschenmoser's salt (dimethylmethylideneammonium iodide). Making use of an easily accessible, nontoxic starting material, this procedure represents a convenient alternative to the original synthetic protocol based on...

Abstract Staggered decamethyl-ferrocene (*Fc) becomes the lower energy conformer at low temperature, whereas eclipsed of ferrocene (Fc) is more stable. The powerful infrared (IR) spectroscopy which has remarkably provided signatures in and staggered conformers recently employed to investigate methylation Fc. most significant consequences full Fc IR spectra are blue shift band ~ 800 cm −1 1500 *...

1,2,4,5-Tetracyanobenzene (TCNB) was reacted with [Cu(dppf)(CH3CN)2](BF4) and [Cu(dchpf)(CH3CN)](BF4), dppf = 1,1'-bis(diphenylphosphino)ferrocene and dchpf = 1,1'-bis(dicyclohexylphosphino)ferrocene, to produce a heterotetranuclear metallamacrocycle 1, {[Cu(dppf)(μ-TCNB)](BF4)}2, and a heterooctanuclear complex 2, [{Cu(dchpf)}4(μ4-TCNB)](BF4)4. Complex 1 is the first example of a structurally ...

A three-component reaction between 1,2-phenylenediamine, ferrocenecarbaldehyde, and isocyanides in the presence of a catalytic amount of p-toluenesulfonic acid for the synthesis of 3,4-dihydroquinoxalin-2-amine derivatives containing a ferrocene unit is reported. This approach is an effective procedure because the products have a broad spectrum of biological and pharmacological activities such ...
