An Enantioselective Oxidative C-H/C-H Cross-Coupling Reaction: Highly Efficient Method to Prepare Planar Chiral Ferrocenes
Gao, De-Wei,Gu, Qing,You, Shu-Li
, p. 2544 - 2547 (2016)
A Pd-catalyzed, asymmetric oxidative cross-coupling reaction between ferrocenes and heteroarenes is described. The process, which takes place via a twofold C-H bond activation pathway, proceeds with modest to high efficiencies (36-86%) and high levels of regio- and enantioselectivity (95-99% ee). In the reaction, air oxygen serves as a green oxidant and excess amounts of the coupling partners are not required. The process is the first example of a catalytic asymmetric biaryl coupling reaction that occurs via double C-H bond activation. Finally, the generated coupling products can be readily transformed into chiral ligands and catalysts.
Triggered Metal Ion Release and Oxidation: Ferrocene as a Mechanophore in Polymers

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.

A series of new push–pull chromophores based on a combined cyclopenta[c]thiophene-4,6-dione (ThDione) acceptor, N,N-dimethylaniline, N-piperidinylthiophene or ferrocene donors, and ethylene or buta-1,3-dienylene π-linkers has been designed and synthesized. Utilizing one or two ThDione acceptors afforded linear or branched push–pull molecules. Experimental and theoretical study of their fundamental properties revealed thermal robustness up to 260 °C, a electrochemical/optical HOMO–LUMO gap that is tunable within the range of 1.47–2.19/1.99–2.39 eV, and thorough elucidation of structure–property relationships. Compared to currently available portfolio of heterocyclic electron-withdrawing units, ThDione proved to be a powerful and versatile acceptor unit. It imparts significant intramolecular charge transfer and polarizes the π-system, which results in enhanced (non)linear optical response.
Synthesis of ferrocene/chitosan-AgNPs films and application in plasmonic color-switching and antimicrobial materials

As a new dialdehyde cross-linking agent, Ferrocene-1,1′-dicarbaldehyde (FcDa) was synthesized and used firstly for chitosan (FcDa/CS) by our group. Silver nanoparticles (AgNPs) were formed in situ by doping the AgNO3 solution into the FcDa/CS film forming solution without adding other reductant because that the Fe(II) of ferrocene has good reducibility. A series of ferrocene-1,1′-dicarbaldehyde)/Chitosan-AgNPs (FcDa/CS-AgNPs) films was prepared by solution casting. The basic structures of FcDa/CS and FcDa/CS-AgNPs were examined by using Fourier transform infrared (FT-IR), X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), and UV–vis spectrophotometer. The FcDa/CS is a layered, rigid and double network structure. According to the XPS energy spectrum data, the energy spectrum shift of ferrocene and the generation of Schiff-base can be observed, which show that FcDa can reduce Ag+ to Ag. Depending on the difference of AgNO3 concentration, the aggregation degree, quantity and size of the obtained AgNPs on the surface of the film were different. By adjusting acid-base environment for realizing the deprotonation/protonation of amino group, the prepared film exhibited the plasmonic color-switching properties from reddish brown to golden yellow. The surface plasmon resonance (SPR) peak of the films under different pH environments shifted from 430 to 464 nm. The cubic silver structure was also observed on the surface micro morphology after the color change of the films. These phenomenons confirmed that this color change was the plasmonic color-switching properties of FcDa/CS-AgNPs films. Additionally, the inhibition zone experiment showed that the FcDa/CS-AgNPs films had antimicrobial activity against Escherichia coli and Staphylococcus aureus. The FcDa/CS-AgNPs films have potential application in smart plasmonic color-switching and antimicrobial materials.
