Enantiomeric-enriched ferrocene-modified pyrazoles were synthesized via the reaction of the ferrocene alcohol, (S)-FcCH(OH)CH3 (Fc = ferrocenyl), with various pyrazoles in acidic conditions at room temperature within several minutes. X-ray structural data for racemic (R,S)-1N-(3,5-dimethyl pyrazolyl)ethyl ferrocene (1) and its (S)-enantiomer (S)-1 were determined. A series of racemic pyrazolylalkyl ferrocenes was separated into enantiomers by analytical HPLC on βand γcyclodextrins (CD) chiral stationary phases. The quantum chemical calculations of interaction energies of βCD were carried out for both (R)- and (S)-enantiomers. A high correlation between experimental HPLC data and calculated interaction energies values was obtained.

A new ferrocene derivative, 1-(1-ferrocenylethyl)-pyridinium (fep = CpFeCp-CH(CH3)-Py+) chloride, and two charge ransfer salts (CTSs) based on the cationic fep donor and Lindqvist ype polyoxometalate acceptors, [fep]2[Mo6O19] (1) and [fep] 2[W6O19] (2), were synthesized. fepCl was characterized by elemental analysis, IR spectroscopy and 1H NMR and the two CTSs were characterized by elemental analysis, IR spectroscopy, UV-vis diffuse reflectance spectrum, cyclic voltammetry, fluorescence spectrum and single crystal X-ray diffraction. X-ray crystallographic studies of the brownish red CTSs 1 and 2 reveal that they are isostructural and crystallize in the monoclinic space group P21/n. In salts 1-2, fep and polyoxoanions are cocrystallized by Coulombic forces, and there also exist the complex C-H?π and π?π stacking interactions between the adjacent fep cations and C-H?O hydrogen bonds between the adjacent fep cations and polyanions. The UV-vis diffuse reflectance spectra indicate the presence of a broad charge ransfer band between 500 and 850 nm for 1-2, and CT character of 1 and 2 is also confirmed by the Mulliken correlation between the CT transition energies and the reduction potentials of the polyoxometalate acceptors. Two new hybrid materials based on 1-(1-ferrocenylethyl)-pyridinium donor and Lindqvist ype polyoxometalate acceptors were synthesized in high yields and their UV-vis diffuse reflectance spectra indicate the presence of a broad charge ransfer band between 500 and 850 nm.

Reductive catalysis with earth-abundant metals is currently of increasing importance and shows potential in replacing precious metal catalysis. In this work, we revealed catalytic hydroboration and hydrosilylation of ketones and aldehydes achieved by a structurally defined manganese(ii) coordination polymer (CP) as a precatalyst under mild conditions. The manganese-catalysed methodology can be applied to a range of functionalized aldehydes and ketones with turnover numbers (TON) of up to 990. Preliminary results on the regioselective catalytic hydrofunctionalization of styrenes by the Mn-CP catalyst are also presented.

Self-cross-linkable ferrocenyl-containing polymethylhydrosiloxanes were synthesized. Karstedt's catalyst and cis-[PtCl2(BnCN)2] were examined as cross-linking catalysts at room temperature for the reaction between Si–H groups of the ferrocenyl-containing polymethylhydrosiloxanes. Cis-[PtCl2(BnCN)2] is an effective catalyst that allows cross-linked ferrocenyl-containing silicones (silicone rubbers) to be obtained with no visible mechanical defects (bubbles or cracks) compared with Karstedt's catalyst. The ferrocene content of the ferrocenyl-containing silicone rubbers was found to be approximately 50?wt.% by energy-dispersive X-ray analysis. Compared with cross-linked non-modified polymethylhydrosiloxanes, the ferrocenyl-containing silicone rubbers exhibited improved tensile properties (the tensile strength increased from 0.47 to 0.75?MPa) and a 1.5–2.5 times lower cross-linking degree. The surface resistivity of the ferrocenyl-containing silicone rubbers (50?wt.% ferrocenyl units) was approximately 7 × 109?Ω/□, which was 10,000 times lower than that of pure polymethylhydrosiloxane. The obtained flexible electroactive ferrocenyl-containing silicone rubbers can potentially be applied as coatings for electronic and electrostatic-sensitive devices, interfaces, and sensors.

The in air catalytic hydroboration of ketones and aldehydes with pinacolborane by an iron(ii) coordination polymer (CP) is carried out under mild and solvent-free conditions. The precatalyst is highly active towards a wide range of substrates including functionalized ketones and aldehydes in the presence of KOtBu as an activator, achieving a high turnover number (TON) of up to 9500. Excellent chemoselectivity to aldehydes over ketones was also revealed, which is in sharp contrast with the results obtained under inert atmosphere using the same catalyst system. This catalyst observed here is not only highly efficient but also recyclable for reuse for at least 5 times without losing its effectiveness.
