Direct synthesis of formic acid from carbon dioxide by hydrogenation in acidic media

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic ...

Conjugation of organoruthenium(II) 3-(1H-benzimidzol-2-yl)-pyrazolo[3,4-b]pyridines and indolo-[3,2-d]benzazepines to recombinant human serum albumin: a strategy to enhance cytotoxicity in cancer cells

Paul Joseph Dyson, Angela Casini, Fabio Edafe

Following our strategy of coupling cyclin-dependent kinase (Cdk) inhibitors with organometallic moieties to improve their physicochemical properties and bioavailability, five organoruthenium complexes (1c-5c) of the general formula [RuCl(eta(6)-arene)(L)]C ...

Understanding Chloroquine Action at the Molecular Level in Antimalarial Therapy: X-ray Absorption Studies in Dimethyl Sulfoxide Solution

Andrzej Sienkiewicz

X-ray absorption spectroscopy is used to determine the local atomic structure around the iron atom from a soluble synthetic analogue of malaria pigment (hemozoin), cf. ferrimesoporphyrin IX of mesohematin anhydride, in the absence or presence of chloroquin ...

BCl3-Mediated Ene Reaction of Sulfur Dioxide and Unfunctionalized Alkenes

Pierre Vogel, Dean Markovic, Chandra Mouleeswara Rao Volla

The first ene reactions of SO2 and unfunctionalized alkenes are reported. Calculations suggest that the endergonic ene reactions of SO2 with alkenes can be used to generate beta,gamma-unsaturated sulfinyl and sulfonyl compounds. Indeed, in the presence of ...

Electrodeposition and Characterization of Bismuth Telluride Nanowires

Simon Granville

In this work, we report thermoelectric measurements on electroplated bismuth telluride nanowires. Porous polycarbonate membranes, obtained by ion-track irradiation lithography, were chosen as electroplating templates. Bismuth telluride nanowires were achie ...

New developments in iron-catalyzed carbon-carbon bond forming reactions

Chandra Mouleeswara Rao Volla

The goal of this thesis is to develop new carbon-carbon bond forming reactions using inexpensive and simple coupling partners like aryl halides (pseudohalides), sulfonyl derivatives, Grignard reagents, alkenes and alkynes with metal catalysis, preferably u ...

Is the aromatic fragment of piano-stool ruthenium compounds an essential feature for anticancer activity? The development of new Ru-II-[9]aneS(3) analogues

Paul Joseph Dyson, Claudine Scolaro

New half-sandwich R-II-[9]aneS(3) complexes ([9]aneS(3) = 1,4,7-trithiacyclononane), namely [RuCl2(PTA)([9]aneS(3))] (4), [RuCl(PTA)(2)([9]aneS(3))][OTf] (5), [RuCl(en)([9]aneS(3))][OTf] (6), [RuCl(enac)([9]aneS(3))][OTf] (7), [RuCl(bipy)([9]ane-S-3)][OTf] ...

Methodology for demonstrating and measuring the photocytotoxicity of fluoranthene to fish cells in culture

Kristin Schirmer

Methodology was developed for quantifying the photocytotoxicity of fluoranthene to a gill cell line from rainbow trout for future use in screening polycyclic aromatic hydrocarbons for their relative photocytotoxicity to fish. Solubilization in a modified c ...

[mono[125I]iodo-Tyr10,MetO17]-vasoactive intestinal polypeptide. Preparation, characterization, and use for radioimmunoassay and receptor binding

Pierre Magistretti, Jean-Luc Martin

Vasoactive intestinal polypeptide (VIP) was labeled with sodium [125I]iodide using the chloramine-T method and subsequently purified by reverse-phase high performance liquid chromatography. Three main 125I-labeled peaks designated A, B, and C resulted from ...

Base Promoted 1,4-Elimination Reactions : On the Origin of an Eventual syn-Stereoselectivity

Rate ratios were obtained for the base-catalyzed 1,4-dehydrochlorination of (E)- and (Z)-Me3CCCl:C:C:CClCMe3 to give Me3CC.tplbond.CC.tplbond.CCMe3. In the KOMe/MeOH or KOCMe3/Me2SO systems the reactivity of both isomers was similar. With KOCMe3 in Me3COH, ...
