Synthesis of Bisheteroarylalkanes by Heteroarylboration: Development and Application of a Pyridylidene?Copper Complex

The development of pyridylidene-Cu-complexes and their application in Cu/Pd-catalyzed heteroarylboration of alkenylheteroarenes is reported. The significance of 1,1?-heteroarylalkanes as building blocks for drug discovery, as well as the straightforward and modular sequence to prepare the pyridylidene-Cu-complexes, makes this catalyst and it applications attractive for chemical synthesis. Furthermore, chiral variants of the pyridylidene-Cu-complexes have been prepared and utilized in the enantioselective arylboration of E-alkenes, further demonstrating the value and potential of this class of catalysts.

Functionalized 1?-Substituted Iodoferrocenes and Their Pd-Catalyzed Heck Cross-Coupling Reactions

This paper describes the preparation of a variety of 1?-substituted iodoferrocenes from 1-iodo-1?-(tri-n-butyltin)ferrocene by an electrophilic substitution of the tri-n-butyltin moiety with functionalized acylium and benzoylium species. Additionally, we demonstrate a Heck coupling protocol for these functionalized iodoferrocenes with ethenylferrocene.

Oxidative ring-opening of ferrocenylcyclopropylamines to N-ferrocenylmethyl beta-hydroxyamides

The in situ reduction of ferrocenyl cyclopropylimines to the corresponding amines triggers a facile oxidative ring-opening to yield the formal four-electron oxidation products: N-ferrocenylmethyl beta-hydroxyamides. This process is believed to proceed via generation of a ferrocinium ion in the presence of air, leading to facile formation of a distonic radical cation that is ultimately trapped by oxygen.

Photoinduced processes of newly synthesized bisferrocene- and bisfullerene-substituted tetrads with a triphenylamine central block

Photoinduced electron transfer processes of two newly synthesized tetrads with a triphenylamine (TPA) as central building block, to which bisfullerenes (C60) and bisferrocenes (Fc) are covalently connected, have been studied. One of them has a TPA linked with one C60 moiety and two ferrocene moieties C60-TPA-(Fc)2 and another tetrad has a TPA linked with two C60 moieties and one ferrocene unit (C60)2-TPA-Fc. The photophysical properties of (C60)m-TPA-(Fc)n have been investigated by applying the picosecond time-resolved fluorescence and nanosecond transient absorption techniques in both polar and nonpolar solvents. The charge separation process via the excited singlet state of the C60 moiety of the C60-TPA-(Fc)2 is more efficient than that of the (C60)2-TPA-Fc. It is found that the ratio of Fc-donor to C60-acceptor affects charge separation efficiency via the excited singlet state of the C60 moiety.

Ion exchange of ferro(ferri)cyanide in polyvinylferrocene films

Ion exchange of ferro/ferricyanide into oxidized polyvinylferrocene (PV-Fc) films occurs upon repetitious cycling of a PV-Fc film between its oxidized and reduced forms in the presence of either Fe(CN)63- and Fe(CN)64-. The ion exchange is evident from cyclic voltammetry and the response of a quartz crystal microbalance coated with a PV-Fc film. Insertion of the multiply charged anions appears to result in deactivation of polyvinylferrocene sites, with the exchanged films initially exhibiting voltammetric waves due to confined ferro(ferri)cyanide. Prolonged cycling of the exchanged films causes complete passivation of the films towards redox species in the film, as well as solution species, suggesting extensive electrostatic cross-linking by the multiply charged anions. Coulometric experiments suggest that approximately one ferro(ferri)cyanide exchanges for three PV-Fc redox sites. The visible spectra of the exchanged films after prolonged cycling suggests the presence of prussian blue-like species in the polymer film which presumably arise from decomposition of the polymer.

Lack of electronic coupling despite half-wave potential splittings in ferrocenylvinyl-substituted [2.2]-paracyclophanes

Pseudo-para bis(ferrocenylvinyl)-[2.2]-paracyclophane 2 and its constitutional isomer 3 have been prepared and investigated with respect to their electrochemical and UV/Vis/NIR spectroelectrochemical properties. Cyclic and Square Wave voltammetric measurements show two consecutive one-electron oxidations with a modest redox splitting of 60 and 84 mV, respectively, for the individual Fc/Fc+ couples. In spite of the redox splitting, radical cations 2+ and 3+ constitute class I mixed-valent systems with no detectable electronic coupling between the individual redox sites. The results are thus very similar to those for the pseudo-ortho isomer 1 +, which was previously reported (J. Organomet. Chem. 2012, 717, 14) but erroneously assigned the pseudo-para structure.

Cation participation during the redox switching of poly(vinylferrocene) films in aqueous 0.05 M perchlorate solutions: Part 1: Cyclic voltammetry and the EQCM

Mobile species transfer accompanying the redox switching of poly(vinylferrocene) (PVF) in aqueous perchlorate solutions of four cations was investigated using the electrochemical quartz crystal microbalance (EQCM). Cyclic voltammetry in 0.05 M solutions containing hydronium, sodium, rubidium or tetraethylammonium cation was employed. The mass transients could not be explained solely in terms of anion and solvent transport processes. EQCM transient data showed that the cation as well as perchlorate and water transport participated in the redox switching process in the four bathing solutions. Results and interpretation of the experimental approach are presented.
