Electrochemical molecularly imprinted polymers (e-MIPs) are reported for the first time. Their elaboration is based on the introduction of a redox tracer (vinylferrocene) inside the binding cavities of a cross-linked MIP. Determination of the analyte (benzo[a]pyrene) can be simply performed by measuring the redox tracer signal. the Partner Organisations 2014.

The synthesis and characterization of a family of air-stable primary, secondary, and tertiary phosphines containing all possible combinations of ethylferrocene and ethylruthenocene substituents are reported. Each phosphine was characterized by 1H, 13C, and 31P NMR spectroscopy, IR and UV-vis absorption spectroscopy, mass spectrometry, and elemental analysis. With the exception of primary ethylruthenocene phosphine 8a, all of the title compounds have been studied by single-crystal X-ray crystallography. Ferrocene-containing phosphines showed maximum absorption at wavelengths of ca. 440 nm and qualitatively reversible oxidation waves in their cyclic voltammograms with intensities scaling to the number of ferrocene units present. The average metal-cyclopentadienyl centroid distances observed for ferrocene-containing phosphines were shorter than those of ruthenocene-containing phosphines, which also had maximum absorption wavelengths of ca. 320 nm and underwent irreversible electrochemical oxidation. Phosphines containing both ethylferrocene and ethylruthenocene substituents displayed properties consistent with the presence of both metallocene types.
Synthesis, characterization and second-order nonlinear optical behaviour of ferrocene-diketopyrrolopyrrole dyads: The effect of alkene: Vs. alkyne linkers

New, thermally stable dipolar ferrocene-diketopyrrolopyrrole (Fc-DPP) dyads with alkene as a linker exhibited structure dependent first hyperpolarizabilities, βHRS, recorded by a femtosecond HRS technique using a femtosecond (120 fs) pulsed laser light system at 900 nm at ambient temperature. On the basis of linear optical, electrochemical and TD-DFT studies, a good structure-polarization relationship has been established to account for the observed trends in first hyperpolarizabilities. The dyads exhibited fluctuating but matching solvatochromism. Nonlinear optical properties are modulated both by the strength of the acceptor as well as the length and nature of the π-conjugation bridge. βHRS of the dyads were compared with structurally related dyads in which the DPP core and the Fc donor are linked via an alkyne bridge. It is interesting to observe that the replacement of an alkyne link with alkene in these D-π-A chromophores does not necessarily furnish enhanced βHRS.

Compounds 1,2-bis[(η5-cyclopentadienyl)dicarbonylnitrosylchromium]ethene (7) (hereafter called 1,2-dicynichrodenylethene) and 1,2-diferrocenylethene (10) were prepared from formylcynichrodene (3) and formylferrocene (9), respectively, via the McMurry's low-valent titanium coupling method. Compounds (η5-vinylcyclopentadienyl)dicarbonylnitrosylchromium (6) and vinylferrocene (11) were obtained by the dehydration of the corresponding alcohols. The structure of 7 was solved by an X-ray diffraction study: space group, P21/c; monoclinic; a=6.379(5), b=11.295(3) and c=11.9352(24); Z=2. It turns out that compound 7 adopts a transoid conformation at the ethenylene bridge and the two cyclopentadienyl rings are coplanar. The nitrosyl group in each cynichrodenyl moiety of 7 is located at the side towards the corresponding ethenylene carbon atom with a twist angle of 46.5°. The chemical shifts of H(2)-H(5) protons and C(2)-C(5) carbon atoms of a series of vinyl derivatives of compounds bearing cyclopentadienyl rings have been assigned using two-dimensional HetCOR-NMR spectroscopy. For the derivatives of cynichrodene (1) and ferrocene, it was found that the shielding of C(2,5) and C(3,4) carbon atoms is parallel to the shielding of the ortho- and para-carbon atoms of benzene derivatives. The electron density distribution in the cyclopentadienyl ring is discussed on the basis of 13C-NMR data. Surprisingly, the vinyl group donates electron density to the adjacent cynichrodene moieties rather than withdraws from them.

Synthesis of ferrocenyl-bearing dendrimers with a resorcinarene core
Valderrama, M.I. Reyes,García, R.A. Vázquez,Klimova,Klimova,Ortiz-Frade,García, M. Martínez
, p. 1597 - 1605 (2008)
A series of ferrocenyl ended dendrons containing π-conjugated systems were obtained using Wittig and Heck reactions. The dendrons were attached to eight functionalized resorcinarenes via Williamson reaction obtaining high molecular weight dendrimers. No electronic communication between metal centers was observed by cyclic voltammetry. All the dendrimers were characterized by 1H, 13C NMR, FTIR, UV-Vis, MALDI-TOF, elemental analyses, and electrochemical studies.

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.
Synthesis of α-arylalkylferrocenes through cesium fluoride-promoted coupling of arylboronic acids with N-tosylhydrazones
Liu, Yueqiang,Ma, Xiaowei,Liu, Yan,Liu, Ping,Dai, Bin
, p. 921 - 928 (2018)
A cesium fluoride-promoted reductive coupling reaction of acylferrocene tosylhydrazones with arylboronic acids has been developed, producing highly substituted α-arylalkylferrocenes in moderate to excellent yields. The reaction employs anionic fluorine to facilitate the cleavage of C–B bond. The developed methodology demonstrates a wide substrate scope and high functional groups tolerance. Moreover, the α-arylalkylferrocenes compounds were also obtained on a multi-gram scale.

The stereochemistry of two processes, viz., α-ferrocenylalkylation of indazole with optically active S-(+)-1-ferrocenylethanol and the thermal rearrangement of S-(+)-2-N-(ferrocenylethyl)indazole into S-(+)-1-N- (ferrocenylethyl)indazole, was studied. Bot

Despite common perception, the use of strong bases in Wittig chemistry is utterly unnecessary: we report a series of novel ion-pair phosphonium carboxylate reagents which are essentially "storable ylides". These reagents are straightforwardly prepared in excellent yields, and their fluxional nature permits clean olefination of a broad range of aldehydes and even hemiacetals.

We report herein a simple catalytic method for the extensive labeling of alkenyl C-H bonds through the combination of a palladium(0) complex and a carboxylic acid in the presence of deuterium oxide. The reaction can be applied to a variety of terminal alkenes and the best results are obtained with aryl-substituted examples. This method represents a convenient approach for the preparation of extensively labeled chemicals from the cheapest and safest source of deuterium.
