Isopropylation of 2-naphthol over mesoporous silicoaluminophosphate-37 (MESO-SAPO-37): Effect of bond dissociation energy on product distribution

03-Feb-2016 | Rekha Yadav; Sakthivel Ayyamperumal, New Journal of Chemistry, 2016

The vapor phase iso-propylation of 2-naphthol (2-NP) with iso-propyl alcohol (IPA) in the presence of recently developed mesoporous silicoaluminophosphate assembled from microporous SAPO-37 precursor (MESO-SAPO-37) was investigated. The bond dissociation energy calculation revealed that the ...


Synthesis of N-heterocyclic carbene–PdCl2–(iso)quinoline complexes and their application in arylamination at low catalyst loadings

02-Feb-2016 | Feng Liu; Yi-Ran Zhu; Lu-Gan Song; Jian-Mei Lu, Organic & Biomolecular Chemistry, 2016

A new type of N-heterocyclic carbene–PdCl2–(iso)quinoline complexes 3 were successfully achieved in acceptable to good yields from easily available starting materials under mild conditions, and their structures were unambiguously confirmed using X-ray single crystal diffraction. Furthermore, ...


Impacts of pH and temperature on soil bacterial 3-hydroxy fatty acids: development of novel terrestrial proxies

31-Jan-2016 | Author(s): Canfa Wang, James Bendle, Yi Yang, Huan Yang, Huiling Sun, Junhua Huang, Shucheng Xie, Organic Geochemistry, 2016

Publication date: Available online 28 January 2016 Source:Organic Geochemistry Author(s): Canfa Wang, James Bendle, Yi Yang, Huan Yang, Huiling Sun, Junhua Huang, Shucheng Xie Gram-negative bacterial 3-hydroxy fatty acids (3-OH-FAs) biomarkers are widespread in a variety of ...


Applications of natural dye from Ixora coccinea L. in the field of textiles and cosmetics

28-Jan-2016 | Nital N Patil, Ajit G Datar, Coloration Technology, 2016

In the present study an attempt has been made to propose the application of natural dye from Ixora coccinea L., commonly known as Jungle geranium, in the field of textiles and cosmetics. Dyeing with I.coccinea colourant with different combinations of mordants resulted in different shades, such ...


Base metal-catalyzed benzylic oxidation of (aryl)(heteroaryl)methanes with molecular oxygen

27-Jan-2016 | Hans Sterckx, Johan De Houwer, Carl Mensch, Wouter Herrebout, Kourosch Abbaspour Tehrani and Bert U. W. Maes, Beilstein Journal of Organic Chemistry, 2016

Abstract The methylene group of various substituted 2- and 4-benzylpyridines, benzyldiazines and benzyl(iso)quinolines was successfully oxidized to the corresponding benzylic ketones using a copper or iron catalyst and molecular oxygen as the stoichiometric oxidant. Application of the protocol ...


Shape selective properties of the Al-fumarate metal–organic framework in the adsorption and separation of n-alkanes, iso-alkanes, cyclo-alkanes and aromatic hydrocarbons

27-Jan-2016 | Belgin Bozbiyik; Jeroen Lannoeye; Dirk E. De Vos; Gino V. Baron; Joeri F. M. Denayer, Physical Chemistry Chemical Physics, 2016

The primary goal of this work is to study the adsorption of a wide range of hydrocarbon adsorbates in the Al-fumarate metal–organic framework in order to identify and explore trends in adsorption behaviour that can be related to the sorbate's molecular properties and as well as the properties of ...


Rhodium‐Catalyzed Bis‐Hydroaminomethylation of Linear Aliphatic Alkenes with Piperazine

26-Jan-2016 | Thomas Seidensticker, Jonas M. Vosberg, Karoline A. Ostrowski, Andreas J. Vorholt, Advanced Synthesis & Catalysis, 2016

Abstract An efficient protocol was developed to prepare a series of dialkylpiperazines via Rh‐catalyzed bis‐hydroaminomethylation of linear aliphatic alkenes with piperazine. The well‐known Rh/Biphephos catalytic system was applied, yielding the desired dialkylpiperazines within six tandem ...


Organocatalysis by an aprotic imidazolium zwitterion: regioselective ring-opening of aziridines and applicable to gram scale synthesis

26-Jan-2016 | Nirnita Chakraborty Ghosal; Sougata Santra; Sudarshan Das; Alakananda Hajra; Grigory V. Zyryanov; Adinath Majee, Green Chemistry, 2016

An imidazole-based zwitterionic-salt, 4-(3-methylimidazolium)butane sulfonate (MBS), has been found to be an efficient organocatalyst for aziridine ring-opening regioselectively by various nucleophiles like indoles, pyrroles, methanol, ethanol, acetic acid and di-iso-propylamine. The reactions ...


E-H (E = B, Si, Ge) Bond Activation of Pinacolborane, Silanes, and Germanes by Nucleophilic Palladium Carbene Complexes

26-Jan-2016 | Cezar Catalin Comanescu; Vlad M. Iluc, Chemical Communication, 2016

The reactivity of two nucleophilic palladium carbenes, [PC(sp2)P]Pd(PMe3) and [PC(sp2)P]Pd(PPh3), [PC(sp2)P] = bis[2-(di-iso-propylphosphino)phenyl]methylene, toward the E-H bond activation of Ph4-nEHn (E = Si, Ge; n = 1-3) and pinacolborane (HBpin) is discussed. Unlike previous reports, both ...


Applicability of the EPR‐test to investigate the sensitization behavior of the heat resistant austenitic stainless steel TP310HCbN after stress relief heat treatment

25-Jan-2016 | S. Schmigalla, S. Schultze, Materials and Corrosion, 2016

The chemical composition of heat resistant austenitic stainless steels, is optimized with regard to reach good mechanical properties and oxidation resistance at higher temperatures. But in some circumstances, before starting up the power plant or during operation these materials can get into ...
