Solar Photothermochemical Reaction and Supercritical CO2 Work up for a Fully Green Process of Preparation of Pure p-Nitrobenzyl Bromide

27-08-2013 | Milan Dinda; Supratim Chakraborty; Supravat Samanta; Chitrangi Bhatt; Subarna Maiti; Sandip Roy; Yogesh Kadam; Pushp ..., Environmental Science & Technology, 2013

It has been reported by us recently that p-nitrobenzyl bromide (PNBBr) can be synthesized from p-nitrotoluene (PNT) in high isolated yield with respect to available bromine in 2:1 Br––BrO3– employed as brominating reagent. The reaction was conducted in ethylene dichloride (EDC) and the substrate ...


Insights into the Mechanism of the Benzoannelated Thieno[3,2-b]furan Halogenation. Importance of HOMO–HOMO Interaction

26-08-2013 | Ausra Vektariene, Journal of Physical Chemistry A, 2013

In this paper the mechanism of the benzoannelated thieno[3,2-b]furan halogenation reaction has been characterized using density functional theory calculations. The solvent effect on the studied reaction is taken into account. A variation in charge, bond length, and bond order in the ...


ChemInform Abstract: Highly Diastereoselective Aminobromination of β‐Methyl‐β‐nitrostyrenes with t‐Butyl N,N‐Dibromocarbamate/t‐Butyl Carbamate as Bromine/Nitrogen Sources.

15-08-2013 | Sheng Chen, Jianlin Han, Guigen Li, Yi Pan, ChemInform, 2013

Abstract The reaction proceeds with high regioselectivity and good diastereoselectivity.


Bromination of hydrocarbons with CBr4, initiated by light-emitting diode irradiation

14-08-2013 | Yuta Nishina, Bunsho Ohtani and Kotaro Kikushima, Beilstein Journal of Organic Chemistry, 2013

Abstract The bromination of hydrocarbons with CBr4 as a bromine source, induced by light-emitting diode (LED) irradiation, has been developed. Monobromides were synthesized with high efficiency without the need for any additives, catalysts, heating, or inert conditions. Action and absorption ...


Utilizing Electronic Effects in the Modulation of BTPhen Ligands with Respect to the Partitioning of Minor Actinides from Lanthanides

14-08-2013 | Ashfaq Afsar; Dominic L Laventine; L Harwood; Michael J Hudson; Andreas Geist, Chemical Communication, 2013

Effects of bromine substitution at the 5 and 5,6-positions of the 1,10-phenanthroline nucleus of BTPhen ligand on their extraction properties for Ln(III) and An(III) cations have been studied. Compared to C5-BTPhen, electronic modulation in BrC5-BTPhen and Br2C5-BTPhen enabled these ligands to be ...


Effect of Molecular Size and Particle Shape on the Terahertz Absorption of a Homologous Series of Tetraalkylammonium Salts

06-08-2013 | Andrew D. Burnett; John Kendrick; Christopher Russell; Jeppe Christensen; John E. Cunningham; Arwen R. Pearson; Edmu ..., Analytical Chemistry, 2013

The absorption coefficient and refractive index have been measured for a homologous series of tetraalkylammonium bromides over the frequency range 0.3–5.5 THz. Spectral features are found to shift to lower frequencies as the molecular mass is increased, as expected. However, to understand the ...


ChemInform Abstract: Palladium‐Catalyzed Bond Reorganization of 1,3‐Diynes: An Entry to Diverse Functionalized 1,5‐Dien‐3‐ynes.

01-08-2013 | Wanqing Wu, Yang Gao, Huanfeng Jiang, Yubing Huang, ChemInform, 2013

Abstract This method can also be used for the introduction of other acyl groups or bromine by replacing Ac2O/HOAc or LiCl with the appropriate reagents.


Materials, Vol. 6, Pages 3035-3063: UV Spectrometric Indirect Analysis of Brominated MWCNTs with UV Active Thiols and an Alkene—Reaction Kinetics, Quantification and Differentiation of Adsorbed Bromine and Oxygen

24-07-2013 | Hanelt, Sven ; Friedrich, Jörg F.; Meyer-Plath, Asmus, Materials, 2013

Indirect UV-absorption spectrometry was shown to be a valuable tool for chemical characterization of functionalized carbon nanotubes (CNTs). It complements data from X-ray photoelectron spectroscopy (XPS) or FTIR analysis since it helps to clarify the type and concentration of functional groups. ...


Dicopper(II) Metallacyclophanes with Electroswitchable Polymethyl‐Substituted para‐Phenylene Spacers

22-07-2013 | Jesús Ferrando‐Soria, María Castellano, Rafael Ruiz‐García, Joan Cano, Miguel Julve, Francesc Lloret, Catalina Ruiz‐ ..., Chemistry - A European Journal, 2013

Abstract Double‐stranded anionic dinuclear copper(II) metallacyclic complexes of the paracyclophane type [Cu2L2]4− have been prepared by the CuII‐mediated self‐assembly of different para‐phenylenebis(oxamato) bridging ligands with either zero‐, one‐, or four‐electron‐donating methyl ...
