Aberrant penetrating posterior descending artery from proximal right coronary artery
Authors: Saremi Farhood , Vorobiof Gabriel 
Published: August 2011

AbstractWe report a rare variant of the posterior descending artery (PDA) in a 51‐year‐old African‐American male discovered in coronary CT angiography. Arising from the proximal right coronary artery near its ostium, the anomalous PDA penetrated posteriorly toward the atrioventricular junction septum, exited through the inferior pyramidal space into the posterior interventricular groove and continued in the groove as a short PDA. Along its course it gave rise to small branches to the medial wall of the right atrium, the atrioventricular node region, and the inferoseptal wall of the right ventricle. Clin.

Rose Bengal‐Grafted Biodegradable Microcapsules: Singlet‐Oxygen Generation and Cancer‐Cell Incapacitation
Authors: Wang Xiao‐Lei , Zeng Yu , Zheng Yan‐Zhen , Chen Jian‐Feng , Tao Xia , Wang Ling‐Xuan , Teng Yan 
Published: August 2011

AbstractRose bengal‐grafted chitosan (RB‐CHI), synthesized through dehydration between amino and carboxyl functional groups under mild conditions, was coated onto the outer layer of preformed biodegradable microcapsules consisting of sodium alginate and chitosan. The fabricated photosensitive microcapsules were characterized by optical microscopy, scanning electron microscopy, and confocal laser scanning microscopy. The assembled materials maintained intact spherical morphology and thus showed good ability to form thin films. Electron spin resonance spectroscopy allowed direct observation of the generation of singlet oxygen (1O2) from photosensitive microcapsules under light excitation at about 545 nm. Furthermore, with increasing light radiation, the content of 1O2 increased, as detected by a chemical probe. In vitro cellular toxicity assays showed that RB‐CHI‐coated photosensitive microcapsules exhibit good biocompatibility in darkness and high cytotoxicity after irradiation, and could provide new photoresponsive drug‐delivery vehicles.
Catalytic Palladium Phosphination: Modular Synthesis of C1‐Symmetric Biaryl‐Based Diphosphines
Authors: Bonnafoux Laurence , Gramage‐Doria Rafael , Colobert Françoise , Leroux Frédéric R. 
Published: August 2011

AbstractA new family of C1‐symmetric bis(diphenylphosphino)biphenyls have been prepared starting from readily available ortho,ortho′‐dihalobiphenyl precursors by a palladium‐catalyzed C–P coupling reaction. This process does not require the use of an additional ligand. To date, the synthesis of such diphosphines, by reaction of an intermediate biphenyldiyl dianion with ClPPh2, mainly afforded the undesired cyclic phosphafluorene derivative. So far, no synthetic pathway has been found to avoid this intramolecular reaction. Herein we report the first general and external‐ligand‐free palladium‐catalyzed phosphination reaction that allows the synthesis of a wide variety of substituted ortho,ortho′‐bis(diphenylphosphino)biphenyls. With the aim of illustrating the scope and efficiency of this methodology, we applied it to the establishment of a straightforward access to C1‐symmetrical analogues of the most powerful ligands used in homogenous catalysis and extended it to more challenging substrates.
How Does CuII Convert into CuI? An Unexpected Ring‐Mediated Single‐Electron Reduction
Authors: Barreca Davide , Fois Ettore , Gasparotto Alberto , Seraglia Roberta , Tondello Eugenio , Tabacchi Gloria 
Published: August 2011

AbstractCuxO (x=1,2) nanomaterials with tailored composition and properties—a hot topic in sustainable technologies—may be fabricated from molecular sources through bottom‐up processes that involve unexpected changes in the metal oxidation state and open intriguing challenges on the copper redox chemistry. How copper(II) sources may lead to copper(I) species in spite of the absence of any explicit reducing agent, and even in the presence of oxygen, is one such question—to date unanswered. Herein, we study copper “reduction without reductants” within one molecule and reveal that the actual reducing agent is abstracted atomic hydrogen. By investigating the fragmentation of a copper(II) precursor for copper oxide nanostructures by combined ESI‐MS with multiple collisional experiments (ESI/MSn) and theoretical calculations, we highlight a copper‐promoted CH bond activation, leading to reduction of the metal center and formation of a CuI‐C‐NCCN six‐membered ring. Such a novel ring system is the structural motif for a new family of cyclic copper(I) adducts, which show a bonding scheme, herein reported for the first time, that may shed unprecedented light on copper chemistry. Beyond the relevance for the preparation of copper oxide nanostructures, the hydrogen‐abstraction/proton‐delivery/electron‐gain mechanism of copper(II) reduction disclosed herein appears to be a general property of copper and might help to understand its redox reactivity.
