Microwave-Assisted Synthesis of Few-Layered MoS2/BiOBr Hollow Microspheres with Superior Visible-Response Photocatalytic Activity for Ciprofloxacin Removal

26-Mar-2015 | Jiexiang Xia; Yuping Ge; Dexiang Zhao; Jun Di; Mengxia Ji; Sheng Yin; Huaming Li; Rong Chen, CrystEngComm, 2015

The BiOBr hollow microspheres attached with single-layered molybdenum disulfide (MoS2) were prepared by ethylene glycol (EG) assisted microwave process in the presence of 1-hexadecyl-3-methylimidazolium bromine ([C16mim]Br). The as-prepared samples are characterized by X-ray diffraction (XRD), ...

Hydrogen‐Bond Mediated Aglycone Delivery (HAD): A Highly Stereoselective Synthesis of 1,2‐cis α‐D‐Glucosides from Common Glycosyl Donors in the Presence of Bromine

12-Mar-2015 | Jagodige P. Yasomanee, Alexei V. Demchenko, Chemistry - A European Journal, 2015

Abstract Described herein is the expansion of the picoloyl protecting‐group assisted H‐bond mediated aglycone delivery (HAD) method recently introduced by our laboratory. At first it was noticed that high α‐stereoselectivity is only obtained with S‐ethyl glycosyl donors and only in the ...

Application of Dual Carbon–Bromine Isotope Analysis for Investigating Abiotic Transformations of Tribromoneopentyl Alcohol (TBNPA)

11-Mar-2015 | Anna Kozell; Yinon Yecheskel; Noa Balaban; Ishai Dror; Ludwik Halicz; Zeev Ronen; Faina Gelman, Environmental Science & Technology, 2015

Many of polybrominated organic compounds, used as flame retardant additives, belong to the group of persistent organic pollutants. Compound-specific isotope analysis is one of the potential analytical tools for investigating their fate in the environment. However, the isotope effects associated ...

Enantioselective Halogenative Semi‐Pinacol Rearrangement: Extension of Substrate Scope and Mechanistic Investigations

25-Feb-2015 | Fedor Romanov‐Michailidis, Maria Romanova‐Michaelides, Marion Pupier, Alexandre Alexakis, Chemistry - A European Journal, 2015

Abstract The present Full Paper article discloses a survey of our recent results obtained in the context of the enantioselective halogenation‐initiated semi‐pinacol rearrangement. Commencing with the fluorination/semi‐pinacol reaction first and moving to the heavier halogens (bromine and ...

Synthesis of 3-Bromosubstituted Pyrroles via Palladium-Catalyzed Intermolecular Oxidative Cyclization of Bromoalkynes with N-Allylamines

25-Feb-2015 | Huanfeng Jiang; Jia Zheng; Liangbin Huang; Zun Li; Wanqing Wu; Jianxiao Li, Chemical Communication, 2015

This paper describes a novel palladium-catalyzed oxidative cyclization of bromoalkynes with N-allylamines via cascade formation of C–N and C–C bonds. During this process, the bromine atom was retained to form 3-bromo-pyrroles, which can undergo the subsequent structural modifications

Synthesis of C6‐Pyridylpurine Nucleosides by Reaction of Nebularine N1‐Oxide with Pyridinyl Grignard Reagents

19-Feb-2015 | Stefano D'Errico, Giorgia Oliviero, Nicola Borbone, Fabrizia Nici, Vincenzo Piccialli, Brunella Pinto, Daniele D'Alo ..., European Journal of Organic Chemistry, 2015

Abstract A general synthesis of C6‐pyridylpurine nucleosides is described. The reported synthetic procedure exploits the regioselective addition of pyridinyl Grignard reagents, obtained by bromine/magnesium exchange between mono‐ or dihalopyridines and iPrMgCl, to the C6–N1–O– moiety of ...

Evaluating the Potential of Halogen Bonding in Molecular Design: Automated Scaffold Decoration Using the New Scoring Function XBScore

19-Feb-2015 | Markus O. Zimmermann; Andreas Lange; Frank M. Boeckler, Journal of Chemical Information and Modeling, 2015

We present a QM-derived empirical scoring function for the interaction between aromatic halogenated ligands and the carbonyl oxygen atom of the protein backbone. Applying this scoring function, we developed an algorithm that evaluates the potential of protein-bound ligands to form favorable ...

Raman spectroscopy of bromine chains inside the one‐dimensional channels of AlPO4‐5 single crystals

18-Feb-2015 | Zhaodong Liu, Mingguang Yao, Ye Yuan, Shuanglong Chen, Ran Liu, Shuangchen Lu, Bo Zou, Tian Cui, Bingbing Liu, Journal of Raman Spectroscopy, 2015

Raman spectroscopy of the one‐dimensional atomic or molecular chains, which are the attractive building blocks of advanced nanoscale materials, is crucial in understanding the physical properties of the one‐dimensional atomic or molecular chains. Here, we introduce the bromine into the ...
