Efficient regio- and diastereo-controlled synthesis of 1,1?- and 1,1?,2,2?-functionalised ferrocenes and the formation of 2-oxa[3]ferrocenophanes

The synthesis of a C2 symmetric 1,1? ,2,2?-tetrasubstituted ferrocene system was discussed. The route involved the reduction of ferrocenyl carbonyl compounds which gave access to a range of alcohols, alkenes, alkanes, ethers, and 2-oxa[3]ferrocenophanes depending on the precise conditions used. The loss of optical activity of 1,1?-bis(hydroxymethyl)ferrocenes and 1,1?-bis(hydroxymethyl)ruthenocenes, which had been prepared by asymmetric reduction, was demonstrated in an acidic medium by extensive 1H NMR studies.

Synthesis and biological properties of Cu(II) complexes with 1,1?-disubstituted ferrocenes

1,1?-Disubstituted ferrocenes have been prepared and used as chelating ligands in the preparation of Cu(II) compounds with a variety of anions such as nitrate, sulfate, oxalate, and acetate. These compounds have been characterized by physical, spectral, and analytical methods. Screening of these derivatives against pathogenic bacterial species such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae showed all of them to possess varied bactericidal activity.

The observation of ion-pairing effect based on substituent effect of ferrocene derivatives

The ion-pairing effect was investigated based on the substituent effect of ferrocene (Fc) derivatives using cyclic voltammetry. It was shown that the presence of ion-pairing strongly affected the electrochemical redox behavior in the organic solvent. The formal redox potential (E0?, the average of anodic and cathodic peak potential) shifted negatively with the increasing ion-pairing effect. That was because the formation of ion pair (Fc+¡¤ClO4-) was beneficial to equilibrium shift from Fc to Fc+ in thermodynamics. In this work, electron-donating and electron-withdrawing substituents of ferrocene derivatives were employed for a deep study of ion-pairing effect, respectively. It is confirmed that both ion-pairing effect and electron-donating substituent effect facilitated the negative shift of E0? for ferrocene derivatives, showing the positive cooperativity. While the electron-withdrawing substituent effect resulted in the positive shift of E0? for ferrocene derivatives and was unfavorable for the oxidation of Fc derivatives, reflecting the negative cooperativity with ion-pairing effect. In addition, the reversal phenomenon of weak electron-withdrawing substituent was revealed when the ion-pairing effect was stronger than the electron-withdrawing substituent effect, indicating that the ion-pairing function has a significant effect on electrochemical behavior of ferrocene derivatives.

Mono-, Di-, and trinuclear palladium(II) complexes containing a ligand with one, two, or three 1,2-dihydroquinazolinium-4-yl groups

Complexes containing one, two, or three 1,2-dihydro-3-xylylquinazolinium-4- yl palladium units are obtained by reacting dialdehydes (C6H 4(CHO)2-1,4, C6H4(CHO) 2-1,3, 1,1?-ferrocenedicarboxaldehyde) or the trialdehyde 1,3,5-tris-(4-formylphenyl)benzene) with 1, 2, or 3 equiv of each of the amino(iminobenzoyl) complex trans-[PdI{C(=NXy)C6H4NH 2-2}(CNXy)2] (Xy = C6H3Me 2-2,6) and triflic acid (HOTf), through a hydroiminiumation of the imine formed between the aldehyde and 2-amino group.

Zinc, cadmium and mercury complexes of redox-active cyanomanganese carbonyl ligands: Intramolecular electron transfer through tetrahedral d10 metal centres

The redox-active cyanomanganese carbonyl ligands cis- and trans-[Mn(CN)(CO)2{P(OR)3}(dppm)] (R = Ph or Et dppm = Ph2PCH2PPh2) reacted with ZnBr2, CdI2 and Hg(NO3)2 to give the tetrahedral (at M) complexes [X2M{(mu-NC)MnLx}2] [MX2 = ZnBr2, CdI2 or Hg(NO3)2; Lx = cis- or trans-(CO)2{P(OR)3}(dppm); R = Ph or Et]; similarly [Mn(CN)(NO)PPh3)(eta-C5H4Me)] gives [X2M{(mu-NC)MnLx}2] {MX2 = ZnBr2 or CdI2 Lx = (NO)-(PPh3)(eta-C5H4Me)}. Treatment of [Br2Zn{(mu-NC)MnLx}2] [Lx = trans-(CO)2{P(OEt)3}(dppm)] 4 with TlPF6 in the presence of 1 or 2 equivalents of trans-[Mn(CN)(CO)2{P(OEt)3}(dppm)] gave the tetra- and penta-metallic complexes [BrZn{(mu-NC)MnLx}3][PF6] 13 and [Zn{(mu-NC)MnLx}4][PF6]2 14 [Lx = trans-(CO)2{P(OEt)3}(dppm)] respectively. Differential pulse volammetry showed that 4, 13 and 14 are oxidised to weakly interacting mixed-valence complexes. The reaction of trans-[Mn(CN)(CO)(dppm)2] with ZnBr2 or CdX2 (X = Br or I) in thf gave the bimetallic species [X2(thf)M(mu-NC)Mn(CO)(dppm)2] (MX2 = ZnBr2 or CdI2) and [Br2Cd(mu-NC)Mn(CO)(dppm)2] which are oxidised by [Fe(eta-C5H5)2][PF6] to the MnII complexes [X2(thf)M(mu-NC)Mn(CO)(dppm)2][PF6] and [Br2Cd(mu-NC)Mn(CO)(dppm)2][PF6]. The crystal structures of the tetrahedral polynuclear complexes [I2Cd{(mu-NC)MnLx}2] [Lx = trans-(CO)2{P(OEt)3}(dppm)] 9 and [Br2(thf)Zn(mu-NC)Mn(CO)(dppm)2] 15 are reported, and the importance of steric effects (as quantified by cone angles) in the behaviour of cyanomanganese carbonyl ligands is noted.

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.

Microcontact Printing Patterning of an HOPG Surface by an Inverse Electron Demand Diels?Alder Reaction

The chemical modification of an sp2 hybridized carbon surface in a controllable manner is very challenging but also crucial for many applications. An inverse electron demand Diels?Alder (IEDDA) reaction using microcontact printing technique is introduced to spatially control the modification of a highly ordered pyrolytic graphite (HOPG) surface under ambient conditions. The covalent modification was characterized by Raman spectroscopy, XPS, and SECM. Tetrazine derivatives can effectively react with an HOPG surface and with microcontact printing methods resulting in spatially patterned surfaces being produced with micrometer-scale resolution.

Resonance Raman studies of selectively labelled hemoglobin tetramers

In this paper, we report the high quality low-frequency resonance Raman (RR) spectra of oxyhemoglobin (oxyHb) and its reconstituted analogs, in which protons in ferric protoporphyrin IX were substituted by deuterium atoms in meso positions (oxyHb-d4), methyl groups (oxyHb-d12), and both meso positions and methyl groups (oxyHb-d16). Analyzed collectively, the RR spectra of the low-spin dioxygen adduct species studied here reveal isotopic-sensitive modes that induce subtle differences in shape of the spectrum of oxyhemoglobins. The most significant spectral differences are observed in the region of 350-440 cm-1 which contains bending modes of the peripheral substituents, i.e. delta(C13,17CcCd) and delta(CCalphaCbeta)+delta(CN) (structure and atom numbering scheme being given in Fig. 1). Several in-plane (nu9, nu25, nu8, nu50, nu33, nu25 and nu48) and out-of-plane (gamma7, gamma16, gamma22, and gamma21) heme vibrations have also been identified. The results presented here provide convincing evidence for the utility of selectively labelled hemoglobins in the definitive assignment of the low-frequency Raman bands.
