Electronic structure and near-IR transitions of FcC2R and FcC4R dyads

This paper describes the orbital configuration which provides a basis for the understanding of the electronic structure and spectroscopic properties of 17e and 18e FcC2R and FcC4R dyads, where R is H, 1-naphthyl, 9-anthryl, 3-pyrenyl, perylenyl. DFT calculations show that destabilisation of the ferrocenyl pi orbitals upon binding a C{triple bond, long}CR group to a Cp ring leads to the metal-based a1 orbital dropping below the e1-a so that the frontier orbital configuration is (e2? -a, pi)2 (e2? -b,metal)2 (e1? -a, pi)2, (a1, metal)2. The contribution of the aryl group to the pi e2-a and e1-a orbitals varies with the annelation of the ring. The LUMO is aryl based. The calculations are consistent with the spectroscopic data for the 18e species. Oxidation to the 17e cations does not change the orbital configuration but the orbital energies are lowered by the positive charge centred on the Fe. A strongly solvatochromic transition in the near-IR, a signature for the 17e cations, is best described as an LMCT transition but the contribution of C2R and C4R to the donor and acceptor levels depends on the ionization energy of the aryl pi orbital. LMCT energies decrease from FcC2R to FcC4R dyads.

C2-Symmetric ferrocenyl bisthiazoles: Synthesis, photophysical, electrochemical and DFT studies

A series of donor-acceptor ferrocenyl substituted bisthiazoles 3-8 were designed and synthesized by the Pd-catalyzed Suzuki, Heck, and Sonogashira cross-coupling reactions. Their photophysical, electrochemical and computational studies reveal strong donor-acceptor interactions. The photonic and electrochemical studies show that the ferrocenyl bisthiazoles with vinyl linkage ferrocenyl-bisthiazole 4, show better electronic communication compared to rest of the ferrocenyl bisthiazoles. The time dependent density functional theory (TD-DFT) calculation at B3LYP on the ferrocenyl substituted bisthiazoles 3-5 was performed, in which the ferrocenyl-bisthiazole 4 shows strong donor-acceptor interactions compared to the Fc-bisthiazoles 3 and 5. The thermal stability of the ferrocenyl substituted bisthiazoles 3-8 is reported, in which Fc-bisthiazole 8 shows high thermal stability. The single crystal structures of ferrocenyl-bisthiazoles 3 and 5 are reported.

Synthesis of ferrocenethiols containing oligo(phenylenevinylene) bridges and their characterization on gold electrodes

Ferrocene-terminated oligo(phenylenevinylene) (OPV) methyl thiols have been prepared by orthogonal coupling of phenylene monomers. Ethoxy substituents on the phenyl rings improve the solubility of OPV, enabling the synthesis of longer oligomers. Self-assembled monolayers containing a mixture of a ferrocene OPV methyl thiol and a diluent alkanethiol were deposited on gold. A cyclic voltammetric study of monolayers containing oligomers of the same length with and without ethoxy solubilizing groups reveals that both solubilized and unsolubilized oligomers form well-packed self-assembled monolayers. Changing the position of the solubilizing groups on an oligomer chain does not preclude packing of the oligomer in the monolayer. Conventional chronoamperometry, which can be used to measure rate constants up to ?104 S-1, is too slow to measure the electron-transfer rate through these oligomers over distances up to 35 A. OPV bridges are expected to be highly conjugated unlike oligo(phenyleneethynylene) bridges, which may be only partially conjugated because of rotation of the phenyl rings about the ethynylene bonds. Because of its high conjugation, OPV may prove useful as a molecular wire.

Alkoxymethylation of ferrocenylalkenes

The reaction of ferrocenylalkenes with chloromethyl alkyl ethers catalyzed by Lewis acids gives 3-alkoxy-1-ferrocenyl carbocations, which can be trapped by nucleophiles to give 1,3-disubstituted ferrocenylalkane derivatives.The application of this reaction to the preparation of chiral 3-hydroxy-1-ferrocenylalkylamines is described; their structures and conformations have been elucidated by NMR spectroscopy.The stereochemical course of the alkoxymethylation reaction involves “exo” attack of the chloromethyl ether at the beta carbon of the double bond relative to the ferrocene, and subsequent “exo” attack of the nucleophile at the carbocationic centre formed in the first step.

Nanoparticle-mediated intervalence transfer

Nanoparticle-mediated intervalence transfer was reported with ferrocene moieties that were attached onto the ruthenium nanoparticle surface by ruthenium-carbene pi bonds. The resulting particles exhibited two pairs of voltammetric waves with a potential spacing of about 200 mV and a rather intense absorption peak in the near-infrared range (?1930 nm) at mixed valence. Both features suggested Class II characteristics of the intraparticle intervalence transfer that mainly arose from through-bond interactions between the metal centers. Quantum calculations based on density functional theory showed that the nanoparticle core electrons served as conducting band states for the effective charge delocalization between particle-bound ferrocene moieties.

Rh(III)-catalyzed Directed C-H Olefination using an oxidizing directing group: Mild, efficient, and versatile

An efficient Rh(III)-catalyzed oxidative olefination by directed C-H bond activation of N-methoxybenzamides is reported. In this mild, practical, selective, and high-yielding process, the N-O bond acts as an internal oxidant. In addition, simply changing the substituent of the directing/oxidizing group results in the selective formation of valuable tetrahydroisoquinolinone products.

THE ADDITION OF 2,4-DINITROBENZENESULFENYL CHLORIDE TO SOME ALKYL-SUBSTITUTED VINYLFERROCENES

The addition of 2,4-dinitrobenzenesulfenyl chloride to alkyl-substituted vinylferrocenes has been investigated in CH2Cl2, 1,1,2,2-tetrachloroethane and acetic acid solutions.Product analyses were carried out by VPC and PMR techniques and reaction rates measured by a spectrophotometric method.The orientation appears to be determined by the structural features of the intermediate episulfonium ion rather than by the site of the primary attack of the electrophile on the starting substrate.A comparison with the results previously obtained with the methoxymercuration reaction has a bearing on the mechanism of the latter reaction.
