The two highly flexible ligands 1,1'-bis(4-phospholanobutyl)ferrocene (5a) and 1,1'-bis(5-phospholanopentyl)ferrocene (5b) reacted with [PtCl2(cod)] (cod = 1,5-cyclooctadiene), [AuCl(tht)] (tht = tetrahydrothiophene) and [{RhCl(CO)2}2] to give the respective chelate complexes cis-[PtCl2(5a,b-κ(2)P,P')] (7a,b), [AuCl(5a,b-κ(2)P,P')] (8a,b) and trans-[RhCl(CO)(5b-κ(2)P,P')] (9b). Treatment of 5a,...

The design of artificially generated channels featuring distinct remote-switchable functionalities is of critical importance for separation, transport control, and water filtration applications. Here, we focus on the preparation of block copolymers (BCPs) consisting of polystyrene-block-poly(2-hydroxyethyl methacrylate) (PS-b-PHEMA) having molar masses in the range of 91 to 124 kg mol−1 with a ...

Screening and early diagnosis are the key factors for the reduction of mortality rate and treatment cost of cancer. Therefore, sensitive and selective methods that can reveal the low abundance of cancer biomarkers in a biological sample are always desired. Here, we report the development of a novel electrochemical biosensor for early detection of breast cancer by using bioconjugated self-assemb...

In the title compound, [FeSn(C(5)H(5))(C(6)H(5))(3)(C(6)H(4)O(2))], the Sn(IV) atom displays a distorted tetra-hedral coordination geometry, provided by one O atom of the monodentate ferrocene-carboxyl-ate ligand [Sn-O = 2.079 (2) Å] and by three C atoms of the three phenyl groups [average Sn-C = 2.130 (4) Å]. No classic hydrogen bonds or inter-molecular inter-actions are observed in the crystal.

We investigated possible anti-diabetic effect of ferrocene-based acyl ureas: 4-ferrocenyl aniline (PFA), 1-(4-chlorobenzoyl)-3-(4-ferrocenylphenyl) urea (DPC1), 1-(3-chlorobenzoyl)-3-(4-ferrocenylphenyl) urea (DMC1), 1-(2-chlorobenzoyl)-3-(4-ferrocenylphenyl) urea (DOC1) and homoleptic cadmium carboxylates: bis (diphenylacetato) cadmium (II) (DPAA), bis (4-chlorophenylacetato) cadmium (II) (CPA...

Efforts have been devoted to synthesize and characterize processable polymers with desired properties. Herein, four different series of aromatic aliphatic terpolyamides were prepared via solution phase polycondensation 4,4′-oxydianiline hexamethylenediamine (HMDA) various diacids chlorides (isophthalyol dichloride, terepthalyol 1, 1′-ferrocene dicarboxylic acid chloride trans-azobenzene-4, 4′-d...

A systematic investigation of fluoride anion binding properties as a function of chelate backbone has been carried out for ferrocene functionalised boronic esters of the types FcB(OR)2 and fc[B(OR)2]2 [Fc = ferrocenyl = (eta5-C5H5)Fe(eta5-C5H4); fc = ferrocendiyl = Fe(eta5-C5H4)2]. Cyclic boronic esters containing a saturated five- or six-membered chelate ring are readily synthesized from ferro...

Adenosine-5'-[gamma-ferrocene] triphosphate is exploited as a co-substrate for the phosphorylation of the surface-immobilized peptide C-SIYRRGSRRWRKL by protein kinase C, in which the gamma-ferrocene phosphate is transferred to the peptide and then detected by cyclic voltammetry.

Two DNA conjugates modified with ferrocene and β-cyclodextrin were prepared as a pair of probes that work cooperatively for DNA sensing, in which the electrochemical signal of ferrocene on one probe was significantly "quenched" by the formation of an inclusion complex with β-cyclodextrin of the other probe on the DNA templates.

This work demonstrates that, in accord with metal catalysis, ferrocene could be an excellent scaffold for organocatalysts. The simple and easily accessible bifunctional ferrocene-based squaramide-phosphine shows high enantioselectivity in the intramolecular Morita-Baylis-Hillman reaction of 7-aryl-7-oxo-5-heptenals, giving a variety of 2-aroyl-2-cyclohexenols in up to 96% ee.
