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 ...

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
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 ...
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 ...
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 ...
18-Feb-2015 | Nils Middendorf, Katharina Krause, Sebastian Höfener, Journal of Computational Chemistry, 2015
Despite the relatively small size of molecular bromine and iodine, the physicochemical behavior in different solvents is not yet fully understood, in particular when excited‐state properties are sought. In this work, we investigate isolated halogen molecules trapped in clathrate hydrate cages. ...
17-Feb-2015 | Ralph E. Sturgeon, Analytical Chemistry, 2015
A unique flow-through photochemical reactor is utilized for the generation of volatile methyl bromide from aqueous solutions of bromide and bromate ions in a medium of 2% acetic acid containing 3000 μg/mL NH4Cl. The volatile product is transported to a thin-film gas–liquid phase separator and ...

Abstract The regioselective bromination of 2‐aminopyridines in 5‐position is achieved using 1‐butylpyridinium bromide as the bromine source and hydrogen peroxide as the oxidant.
29-Jan-2015 | Somraj Guha; Venkatachalam Rajeshkumar; Surya Srinivas Kotha; Govindasamy Sekar, Organic Letters, 2015
A metal-free one-pot strategy has been developed for the first time to synthesize pharmaceutically important α-amino ketones from readily available benzylic secondary alcohols and amines using N-bromosuccinimide. This new reaction proceeds via three consecutive steps involving oxidation of ...
