The synthesis, electrochemical, optical, and cation sensing properties of a bis(macrocyclic) dye 1, in which the benzo-15-crown-5 and phenylazathia-15- crown-5 subunits are linked through a styryl pyridinium moiety, are reported. In this new ditopic receptor, the benzo-15-crown-5 macrocycle acts as a highly selective binding site for alkaline earth metal cations (MgII and BaII), whereas the phenylazathia-15-crown-5 displays a strong binding affinity towards soft heavy-metal cations (HgII and AgI). The pronounced changes of the absorption and fluorescence spectra of this bichromophoric dye observed upon different metal cation addition make the dye suitable for dual-wavelength analysis and offer an enticing potential for multitasking sensors.

Measurements of the difference absorption spectra were made for 12 phenols and 11 aromatic amines. Aqueous solutions of the same concentration and pH values 8-13 and 1-2 were measured against each other. The difference spectra were found to have a similar run within the group of compounds: monohydroxyl phenols, naphthols, quinolines, aniline and its derivatives and pyridine and its derivatives. The spectra reflect the changes in the conjugated bond systems caused by shifts in acid-base equilibria of the compounds examined.

Synthetic and kinetic studies of the reactions between (Fe(1-5-eta-C6H7)(CO)3)+ (1) and X-substituted pyridines (X=H, 2-Me, 3-Me, 4-Me, 4-Ph, 2-Cl, 3-CN, 2,5-Me2, 2,6-Me2, 3,5-Me2, or 2,4,6-Me3) in CH3CN provide the first quantitative information on the importance of basicity and steric properties in controlling amine nucleophilicity towards co-ordinated ?-hydrocarbons.The products are pyridinium adducts of tricarbonyl(hexa-1,3-diene)iron.Similar pyridinium adduct formation occurs with cations (Fe(1-5-eta-2-MeOC6H6)(CO)3)+ (2) and (Fe(1-5-eta-C7H9)(CO)3)(BF4) (3).The general rate law rate = k1(Fe)(amine) is observed, except for the equilibrium reaction of (1) with 3-cyanopyridine which gives rate = k1 (Fe)(amine) + k-1 (Fe).The rate trend C6H7 > 2-MeOC6H6 > C7H9 found with several pyridines and the low DeltaH1<*> and large negative DeltaS1<*> values are consistent with direct addition to the dienyl rings.For attack of non-sterically crowded pyridines on (1), a Bronsted plot of log k1 versus pKa of the amine conjugate acid has a high slope alpha of 1.0, indicating a very marked dependence of rate on amine basicity.Successive blocking of the 2- and 6-positions of pyridine by methyl groups leads to marked non-additive steric retardation.

This study investigates the effect of three new platinum complexes: Pt2(2,4-dimethylpyridine)4(berenil)2 (Pt14), Pt2(3,4-dimethylpyridine)4(berenil)2 (Pt15) and Pt2(3,5-dimethylpyridine)4(berenil)2 (Pt16) on growth and viability of breast cancer cells and their putative mechanism(s) of cytotoxicity. Cytotoxicity was measured with MTT assay and inhibition of [3H]thymidine incorporation into DNA in both breast cancer cells. Results revealed that Pt14?Pt16 exhibit substantially greater cytotoxicity than cisplatin against MCF-7 and MDA-MB-231 breast cancer cells. In the case of human skin fibroblast cell, cytotoxicity assays demonstrated that these compounds are less toxic to normal cells than cisplatin. In addition, the effects of Pt14?Pt16 are investigated using the flow cytometry assessment of annexin V binding, analysis of mitochondrial potential, markers of apoptosis such as caspase-3, caspase-8, caspase-9, caspase-10 and defragmentation of DNA by TUNEL assay. These results indicate that Pt14?Pt16 induce apoptosis by the mitochondrial and external pathway.

This review summarizes the progress in organo-f-element chemistry during the year 2015. The year 2015 witnessed a slight increase of contributions in the fields of organolanthanide and organoactinide chemistry over 2014 (ca. 10% more). A continuing trend for many years which continued into 2015 was the investigation of highly reactive lanthanide alkyl complexes supported by non-cyclopentadienyl ligands (e.g. amidinates, beta-diketiminates etc.). Many of these complexes found useful applications in homogeneous catalysis. Trinuclear rare-earth metal methylidene (CH22-) complexes are an emerging class of compounds that serve as methylidene transfer agents for the methylenation of carbonyl compounds. The range of rare-earth metal alkyl complexes bearing different types of carbene ligands have also been further expanded. Several new lanthanide phosphido and phosphinidene complexes have been stabilized by specially designed N,N’-chelating ligands. The range of fully characterized lanthanide(II) compounds of the type [K(2.2.2-cryptand)][Cp’3Ln] (Cp’=C5H4SiMe3) has again been significantly expanded so that the +2 ions are now available for yttrium and all the lanthanides (except promethium, which was not studied due to its high radioactivity). The first well-defined lutetacyclopentadienes have been synthesized and their reactivity has been studied. The synthesis, structure, and reactivity of the extremely reactive yttrium metallocene ethyl complex Cp*2Y(CH2CH3), including activation of methane, have been reported. Significant progress has also been made in the field of endohedral metallofullerenes. Notably, encapsulation of a large La2C2 cluster inside D5(450)C100 induced a 5% axial compression of the cage, as compared with the structure of La2@D5(450)C100. The number of well-characterized heterometallic organolanthanide complexes has also witnessed a remarkable growth. An impressive number of interesting contributions have been published in the field of organolanthanide catalysis, with an emphasis on Ln-catalyzed olefin and diene polymerization. Approximately 20% of the papers published in 2015 were in the area of organoactinide chemistry. Notable results include the synthesis and characterization of homoleptic uranium(IV) tetrabenzyl complexes and a simple mono(imido) thorium complex and the first bis(imido) thorium complex, K[Th(NDipp))(NR2)3] and K2[Th(NDipp)2)(NR2)2] (Dipp=2,6-diisopropylphenyl, R=SiMe3). The reactivity of the unusual base-free imido complex [eta5-1,2,4-(Me3C)3C5H2]2ThN(p-tolyl) has also been studied. A highly remarkable achievement in 2015 was the synthesis of crystalline molecular complexes of the [{C5H3(SiMe3)2}3Th]- anion containing thorium in the formal +2 oxidation state. Various unusual transformations have been achieved using the Cp*2Th platform. For example, a unique thorium phosphinidene complex obtained from the reaction of Cp*2Th(CH3)2 with H2P(2,4,6-iPr3C6H2) has been prepared and structurally characterized. Other remarkable results include the preparation of novel actinide metallacyclocumulenes and metallacyclopentadienes. The synthesis of [3]thoro- and [3]uranocenophanes, the first structurally authenticated ansa-bridged actinocenes, has also been reported. Finally, significant progress has been made in the field of organoactinide catalysis.

Linear relationships between sspKa values in acetonitrile-water mixtures and wwpKa values in pure water have been established for five families of compounds: aliphatic carboxylic acids, aromatic carboxylic acids, phenols, amines, and pyridines. The parameters (slope and intercept) of the linear correlations have been related with acetonitrile-water composition. The proposed equations allow accurate estimation of the pKa values of any member of the studied families at any acetonitrile-water composition up to 60% of acetonitrile in volume (100% for pyridines). Conversely, the same equations can be used to estimate aqueous pKa values from chromatographic pKa values obtained from any acetonitrile-water mobile phase between the composition range studied. Estimation of pKa values have been tested with chromatographic literature data.

The synthesis, characterization, DNA interaction and antiproliferative behavior of new pi-arene ruthenium(II) piano-stool complexes with nitrogen ligands are described. Three series of organometallic compounds of formulae [RuCl2(eta6-p-cym)L] were synthesized (with L = 2-, 3- or 4-methylpyridine; L = 2,3-, 2,4-, 2,5-, 3,4-, 3,5-dimethylpyridine and L = 1,2-, 1,3- 1,4-methylaminobenzene). The crystal structures of [RuCl 2(p-cym)(4-methylpyridine)], [RuCl2(p-cym)(3,4- dimethylpyridine)] and [RuCl2(p-cym)(1,4-methylaminobenzene)] were resolved and the characterization was completed by spectroscopic UV-vis, FT-IR and 1H NMR studies. Electrochemical experiments were performed by cyclic voltammetry to estimate the redox potential of the Ru(II)/Ru(III) couple. The interaction with plasmid pBR322 DNA was studied through the examination of the electrophoretical mobility and atomic force microscopy, and interaction with ct-DNA by circular dichroism, viscosity measurements and fluorescence studies based on the DNA-ethidium bromide complex. The antiproliferative behavior of the series with L = methylpyridine was assayed against two tumor cell lines, i.e. LoVo and MiaPaca. The results revealed a moderate cytotoxicity with a higher activity for the LoVo cell line compared to the MiaPaca one.

Metal?metal bonds play a vital role in stabilizing key intermediates in bond-formation reactions. We report that binuclear benzo[h]quinoline-ligated NiII complexes, upon oxidation, undergo reductive elimination to form carbon?halogen bonds. A mixed-valent Ni(2.5+)?Ni(2.5+) intermediate is isolated. Further oxidation to NiIII, however, is required to trigger reductive elimination. The binuclear NiIII?NiIII intermediate lacks a Ni?Ni bond. Each NiIII undergoes separate, but fast reductive elimination, giving rise to NiI species. The reactivity of these binuclear Ni complexes highlights the fundamental difference between Ni and Pd in mediating bond-formation processes.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.
