Published: January 2014

ObjectivesTo determine whether contrast administration was a risk factor for development of acute kidney injury (AKI) in cyanotic congenital heart disease (CHD) patients undergoing cardiopulmonary bypass (CPB).BackgroundAKI following CPB or contrast administration is well described. In previous studies, administration of contrast prior to CPB has been shown to increase the risk of AKI. Chronic cyanosis leads to glomerular damage and dysfunction, thus potentially placing this population at increased risk of developing AKI following contrast administration prior to CPB.MethodsOne hundred twenty‐two patients with cyanotic CHD undergoing preoperative cardiac catheterization (PCC) and subsequent CPB at Children's Medical Center of Dallas from January 1, 2007 until November 30, 2010 were identified, looking specifically at bi‐directional Glenn (BDG) anastomoses and Fontan procedures. One hundred thirteen patients undergoing PCC ≤ 48 hr prior to and > 5 days prior to CPB were included. Occurrence of AKI following CPB was the primary outcome variable.ResultsLogistic regression analysis revealed pre‐catheterization serum creatinine was a risk factor for post‐CPB AKI (P < 0.001) in both Fontan and BDG patients. All other variables were not significantly associated with the development of AKI in either BDG or Fontan patients. Length of stay (hospital or ICU) was not different among the groups regardless of the occurrence of AKI.ConclusionsIn this study of cyanotic CHD patients, contrast administration within 48 hr prior to CPB was not an additional risk factor for the development of AKI. © 2014 Wiley Periodicals, Inc.
Tip of iceberg: when unusual vision complaints with a normal examination prompt a closer look
Authors: Weiss Kathleen D. , Chang Ta C. , Cavuoto Kara M. 
Published: January 2014

Key Clinical MessageNonorganic vision loss (NOVL) is a relatively common condition in pediatric patients. Prompt diagnosis can prevent costly, time‐consuming, and frustrating workups. It is valuable for general practitioners and specialists alike to include NOVL in their differential when evaluating patients with visual complaints that are inconsistent with normal examination findings.
On the Catalysis of the Cycloisomerization of 1,6‐Dienes with Tin(IV) Salts: The Important Role of a Water Molecule

Published: January 2014

AbstractA diene cycloisomerisation reaction catalysed by tin(IV) triflimidate is studied by using DFT computations. It is proposed that the mechanism does not involve the direct addition of the tin(IV) cation to a double bond because the catalyst regeneration step would be energetically unfeasible. We show that a water molecule may play a decisive role to enable the smooth completion of the catalytic cycle. The proposed active catalyst is thus a hydrated triflimidate salt. The hydrolysis and hydration energies are computed for three ligands of SnL4, L=triflate (OTf), triflimidate (NTf2) and a chlorosulfonate model (OSO2Cl). The diastereoselectivity observed in the cycloisomerisation is discussed in light of the transition‐state geometries. The hypothesis of hidden Brønsted acid catalysis is discussed and ruled out on the basis of new experimental results.
Paradigm Shift from Alkaline (Earth) Metals to Early Transition Metals in Fluoroorganometal Chemistry: Perfluoroalkyl Titanocene(III) Reagents Prepared via Not Titanocene(II) but Titanocene(III) Species

Published: January 2014

AbstractPerfluoroalkyl (RF) titanocene reagents [Cp2TiIIIRF] synthesized via [Cp2TiIIICl] rather than [Cp2TiII] show new types of perfluoroalkylation reactions. The [Cp2TiIIIRF] reagents exhibit a wide variety of reactivity with carbonyl compounds including esters and nitriles, and selectivities far higher than those reported for conventional RFLi and RFMgX reagents.
A Stable Microporous Mixed‐Metal Metal–Organic Framework with Highly Active Cu2+ Sites for Efficient Cross‐Dehydrogenative Coupling Reactions
Authors: Yang Xiu‐Li , Zou Chao , He Yabing , Zhao Min , Chen Banglin , Xiang Shengchang , O'Keeffe Michael , Wu Chuan‐De 
Published: January 2014

AbstractTwo metalloporphyrin octacarboxylates were used to link copper(II) nodes for the formation of two novel porous mixed‐metal metal–organic frameworks (M′MOFs) containing nanopore cages (2.1 nm in diameter) or nanotubular channels (1.5 nm in diameter). The highly active Cu2+ sites on the nanotubular surfaces of the stable porous M′MOF ZJU‐22, stabilized by three‐connected nets, lead to the superior catalytic activity for the cross‐dehydrogenative coupling (CDC) reaction.

Published: January 2014

AbstractBinary Pd–polyoxometalates [Pd(dpa)2]3[PW12O40]2⋅12 DMSO (2), [Pd(dpa)2]3[PMo12O40]2⋅12 DMSO⋅2 H2O (3), and [Pd(dpa)(DMSO)2]2[HPMo10V2O40]⋅4 DMSO (4) were synthesized by reaction of [Pd(dpa)(OAc)2]⋅2 H2O (1; dpa=2,2′‐dipyridylamine) with three Keggin‐type polyoxometalates and fully characterized by single‐crystal and powder XRD analyses, IR spectroscopy, and elemental analyses. The synthesis is facile and straightforward, and the complicated ligand‐modification procedure often used in the traditional charge‐transfer method can be omitted. In 2–4, Pd complexes and polyoxometalate anions are coupled through electrostatic interaction. Compound 4 is more active than the other three compounds in the selective aerobic oxidation of alcohols at ambient pressure. Interestingly, during catalytic recycling of compound 4, unprecedented ternary Pd–V–polyoxometalate [Pd(dpa)2{VO(DMSO)5}2][PMo12O40]2⋅4 DMSO (5), which was captured and characterized by single‐crystal XRD, proved to be the true active species and showed high catalytic activity for the selective aerobic oxidation of aromatic alcohols (98.1–99.8 % conversion, 91.5–99.1 % selectivity). Moreover, on the basis of control experiments and EPR and UV/Vis spectra, a plausible reaction mechanism for the oxidation of alcohols catalyzed by 5 was proposed.
Enantioselective Continuous‐Flow Production of 3‐Indolylmethanamines Mediated by an Immobilized Phosphoric Acid Catalyst
Authors: Osorio‐Planes Laura , Rodríguez‐Escrich Carles , Pericàs Miquel A. 
Published: January 2014

AbstractA polystyrene‐supported 1,1’‐bi‐2‐naphthol derived phosphoric acid has been synthesized and applied in the enantioselective Friedel–Crafts reaction of indoles and sulfonylimines. The immobilized catalyst was highly active and selective, and gave rise to a broad range of 3‐indolylmethanamines (19 examples) in high yields and excellent enantioselectivities (up to 98 % enantiomeric excess) after short reaction times under very convenient reaction conditions (RT in dichloromethane). Moreover, repeated recycling (14 cycles) was possible with no substantial loss in catalytic performance and the system could be adapted to a continuous‐flow operation (6 h). Finally, the applicability of the system was further confirmed by rapid access to a library of compounds with three points of diversity in a single continuous‐flow experiment that involved sequential pumping of different substrate combinations.
Surface Chemistry on Small Ruthenium Nanoparticles: Evidence for Site Selective Reactions and Influence of Ligands

Published: January 2014

AbstractThe reactivity of two classes of ruthenium nanoparticles (Ru NPs) of small size, either sterically stabilized by a polymer (polyvinylpyrrolidone, PVP) or electronically stabilized by a ligand (bisdiphenylphosphinobutane, dppb) was tested towards standard reactions, namely CO oxidation, CO2 reduction and styrene hydrogenation. The aim of the work was to identify the sites of reactivity on the nanoparticles and to study how the presence of ancillary ligands can influence the course of these catalytic reactions by using NMR and IR spectroscopies. It was found that CO oxidation proceeds at room temperature (RT) on Ru NPs but that the system deactivates rapidly in the absence of ligands because of the formation of RuO2. In the presence of ligands, the reaction involves exclusively the bridging CO groups and no bulk oxidation is observed at RT under catalytic conditions. The reverse reaction, CO2 reduction, is achieved at 120 °C in the presence of H2 and leads to CO, which coordinates exclusively in a bridging mode, hence evidencing the competition between hydrides and CO for coordination on Ru NPs. The effect of ligands localized on the surface is also evidenced in catalytic reactions. Thus, styrene is slowly hydrogenated at RT by the two systems Ru/PVP and Ru/dppb, first into ethylbenzene and then into ethylcyclohexane. Selectively poisoning the nanoparticles with bridging CO groups leads to catalysts that are only able to reduce the vinyl group of styrene whereas a full poisoning with both terminal and bridging CO groups leads to inactive catalysts. These results are interpreted in terms of location of the ligands on the particles surface, and evidence site selectivity for both CO oxidation and arene hydrogenation.
The First Europium(III) β‐Diketonate Complex Functionalized Polyhedral Oligomeric Silsesquioxane
Authors: Chen Xiaofan , Zhang Panning , Wang Tianren , Li Huanrong 
Published: January 2014

AbstractThe first europium(III) β‐diketonate complex functionalized polyhedral oligomeric silsesquioxane (POSS) has been obtained by immobilization of such a complex at a silicon vertex of the POSS cage through the complexation of Eu3+ ions with thenoyltrifluoroacetone‐functionalized POSS. The new molecular hybrid material is liquid at room temperature, and shows bright‐red emission when irradiated with UV light due to energy transfer from the thenoyltrifluoroacetone ligand to the coordinated Eu3+ ions. Thermal analysis has revealed a significant improvement in the thermal stability of the material compared with tris(2‐thenoyltrifluoroacetonate)europium(III) dihydrate, [Eu(TTA)3]⋅2 H2O. In the context of recent advances in printable electronic technology, this novel luminescent organic liquid with the characteristic emission of Eu3+ may potentially be useful in the development of next‐generation organic devices such as flexible displays.

Published: January 2014

AbstractA general synthetic route to indoles from readily available anilines and epoxides by using ruthenium catalysis is described. This straightforward transformation allows a variety of indoles to be obtained in good yields by using [Ru3(CO)12]/1,1′‐bis(diphenylphosphino)ferrocene as the catalytic system. Water and hydrogen are formed as the only stoichiometric by‐products, making this process highly atom efficient.
