Iridium‐Catalyzed Hydrogenation of Carboxylic Acid Esters
Authors: Junge Kathrin , Wendt Bianca , Jiao Haijun , Beller Matthias 
Published: September 2014

AbstractThe first selective iridium‐catalyzed hydrogenations of esters are presented. By using a commercially available iridium pincer complex more than 20 different aromatic, aliphatic, and (hetero)cyclic esters are reduced to the corresponding alcohols in moderate to very good yields. An outer‐sphere mechanism is proposed on the basis of our computational analysis.
Effects of Contamination and Power‐Law Fluid Viscosity on Heat Transfer Phenomena of Spherical Bubbles
Authors: Nalajala Venkata Swamy , Kishore Nanda 
Published: September 2014

AbstractHeat transfer phenomena of spherical bubbles in unbounded contaminated power‐law liquids were numerically studied within the framework of a stagnant spherical cap model by solving the governing conservation equations of mass, momentum, and energy using a segregated approach. The governing equations were solved with the semi‐implicit method for pressure‐linked equations. The momentum terms were discretized by quadratic upstream interpolation for convective kinematics. Isotherm contours reveal that the thermal boundary layer becomes thinner with the decreasing power‐law index and/or the stagnant cap angle. The surface Nusselt number distributions indicate a sudden decrease at the leading edge of the stagnant cap and this reduction is found to be a strong function of all pertinent parameters. The average Nusselt numbers of contaminated spherical bubbles rise with the smaller cap angle and/or the lower power‐law index.

Published: September 2014

AbstractSix substitutionally inert [RuII(bipy)2dppz]2+ derivatives (bipy=2,2′‐bipyridine, dppz=dipyrido[3,2‐a:2′,3′‐c]phenazine) bearing different functional groups on the dppz ligand [NH2 (1), OMe (2), OAc (3), OH (4), CH2OH (5), CH2Cl (6)] were synthesized and studied as potential photosensitizers (PSs) in photodynamic therapy (PDT). As also confirmed by DFT calculations, all complexes showed promising 1O2 production quantum yields, well comparable with PSs available on the market. They can also efficiently intercalate into the DNA double helix, which is of high interest in view of DNA targeting. The cellular localization and uptake quantification of 1–6 were assessed by confocal microscopy and high‐resolution continuum source atomic absorption spectrometry. Compound 1, and especially 2, showed very good uptake in cervical cancer cells (HeLa) with preferential nuclear accumulation. None of the compounds studied was found to be cytotoxic in the dark on both HeLa cells and, interestingly, on noncancerous MRC‐5 cells (IC50>100 μM). However, 1 and 2 showed very promising behavior with an increment of about 150 and 42 times, respectively, in their cytotoxicities upon light illumination at 420 nm in addition to a very good human plasma stability. As anticipated, the preferential nuclear accumulation of 1 and 2 and their very high DNA binding affinity resulted in very efficient DNA photocleavage, suggesting a DNA‐based mode of phototoxic action.
Chemical Speciation of Uranium(VI) in Marine Environments: Complexation of Calcium and Magnesium Ions with [(UO2)(CO3)3]4− and the Effect on the Extraction of Uranium from Seawater
Authors: Endrizzi Francesco , Rao Linfeng 
Published: September 2014

AbstractThe interactions of Ca2+ and Mg2+ with [UO2(CO3)3]4− were studied by calcium ion selective electrode potentiometry and spectrophotometry. The stability constants of ternary Ca‐UO2‐CO3 and Mg‐UO2‐CO3 complexes were determined with calcium ion selective electrode potentiometry and optical absorption spectrophotometry, respectively. The enthalpies of complexation for two successive complexes, [CaUO2(CO3)3]2− and [Ca2UO2(CO3)3](aq), were determined for the first time by microcalorimetry. The data help to revise the speciation of uranium(VI) species under seawater conditions. In contrast to the previously accepted assumption that the highly negatively charged [UO2(CO3)3]4− is the dominant species, the revised speciation indicates that the dominant aqueous uranium(VI) species under seawater conditions is the neutral [Ca2UO2(CO3)3](aq). The results have a significant impact on the strategies for developing efficient sorption processes to extract uranium from seawater.
Evaluating the Thermal Vinylcyclopropane Rearrangement (VCPR) as a Practical Method for the Synthesis of Difluorinated Cyclopentenes: Experimental and Computational Studies of Rearrangement Stereospecificity
Authors: Orr David , Percy Jonathan M. , Tuttle Tell , Kennedy Alan R. , Harrison Zoë A. 
Published: September 2014

AbstractVinyl cyclopropane rearrangement (VCPR) has been utilised to synthesise a difluorinated cyclopentene stereospecifically and under mild thermal conditions. Difluorocyclopropanation chemistry afforded ethyl 3‐(1′(2′2′‐difluoro‐3′‐phenyl)cyclopropyl) propenoate as all four stereoisomers (18a, 18b, 22a, 22b) (all racemic). The trans‐E isomer (18a), prepared in 70 % yield over three steps, underwent near quantitative VCPR to difluorocyclopentene 23 (99 %). Rearrangements were monitored by 19F NMR (100–180 °C). While cis/trans cyclopropane stereoisomerisation was facile, favouring trans‐isomers by a modest margin, no E/Z alkene isomerisation was observed even at higher temperatures. Neither cis nor trans Z‐alkenoates underwent VCPR, even up to much higher temperatures (180 °C). The cis‐cyclopropanes underwent [3,3]‐rearrangement to afford benzocycloheptadiene species. The reaction stereospecificity was explored by using electronic structure calculations, and UB3LYP/6‐31G* methodology allowed the energy barriers for cyclopropane stereoisomerisation, diastereoisomeric VCPR and [3,3]‐rearrangement to be ranked in agreement with experiment.

Published: September 2014

AbstractTwo new dinuclear copper(II) metallacyclophanes with 1,4‐disubstituted 9,10‐anthraquinonebis(oxamate) bridging ligands are reported that can reversibly take and release electrons at the redox‐active ligand and metal sites, respectively, to give the corresponding mono‐ and bis(semiquinonate and/or catecholate) CuII2 species and mixed‐valent CuII/CuIII and high‐valent CuIII2 ones. Density functional calculations allow us to give further insights on the dual ligand‐ and metal‐based character of the redox processes in this novel family of antiferromagnetically coupled di‐ copper(II) anthraquinophanes. This unique ability for charge storage could be the basis for the development of new kinds of molecular spintronic devices, referred to as molecular magnetic capacitors (MMCs).
