The title complexes [mu-(E)-4,4'-(ethene-1,2-diyl)dipyridine-kappa(2)N:N']bis[halotris(4-methylphenyl)tin(IV)], [Sn(2)(C(7)H(7))(6)X(2)(C(12)H(10)N(2))], where halo is chloro (X = Cl) and bromo (X = Br) are isostructural. In both crystals, the molecules lie on inversion centers, and there are voids of ca 80 A(3) that could, but apparently do not, accommodate water molecules. The corresponding i...

BiFeO3 (BFO), Bi0.86Sm0.07Eu0.07FeO3 (BSEFO), and Bi0.86Sm0.07Cd0.07FeO3 (BSCFO) nano powders were prepared by the sol-gel combustion method and the catalytic performances were evaluated in the acetylation reaction of benzyl alcohol. The physical chemical properties of the catalysts were character...

In this study, TiO2-10%wt. carbon nanotube (CNT) nanocomposite powders were synthesized by sol-gel method at various hydrolysis rate affected by different reaction agents of acetyl acetone and benzyl alcohol. Crystallization of TiO2 was then achieved through calcination at 400 °C. The properties of nanocomposite powder investigated by scanning electron microscopy, X-ray diffraction and diffuse ...

We describe the functionalization of α-amino C-H bonds with aryl halides using a combination of nickel and photoredox catalysis. This direct C-H, C-X coupling uses inexpensive and readily available starting materials to generate benzylic amines, an important class of bioactive molecules. Mechanistically, this method features the direct arylation of α-amino radicals mediated by a nickel catalyst...

The Cover Feature shows “N-amino Benz” (N-(aminobenzyliden)- phthalimide) the protagonist of this article as an enthusiastic young scientist sharing his work. He a molecular redox catalytic reductive reaction discovered with benzyl bromides and chlorides to produce radicals more experienced colleagues in area at informal seminar. After all, it is not that usual have new organic mediator for red...

To date more than 3650 organohalogen compounds are known to be naturally produced by biogeochemical processes [1]. The current understanding of the abiotic formation of organohalogens during early diagenetic processes in soils and sediments are reviewed. Next to volatile alkyl halides and polar organohalogens such as haloacetates there is evidence that even semivolatile organohalogens (e.g. pol...

Accurate calculations are made for the hydration energies of the alkali halides, using the most recent data. These results, and the average of theoretical calculations made by others for the individual ions, are used to determine the most probable hydration energy of the individual ions. These in turn are the basis for calculating the absolute enthalpy of formation of aqueous H: 98.6 kcal/g-equ...

N-Bromosuccinimide completely inactivated the cellulase, and titration experiments showed that oxidation of one tryptophan residue per cellulase molecule coincided with 100% inactivation. CM-cellulose protected the enzyme from inactivation by N-bromosuccinimide. The cellulase was inhibited by active benzyl halides, and reaction with 2-hydroxy-5-nitrobenzyl bromide resulted in the incorporation ...

Very recently, a series of papers dealing with the reduction of organic halides at silver cathodes have appeared. The most important result emerging from such studies is that silver exhibits extraordinary electrocatalytic activities towards the reduction process, especially in the case of bromides and iodides. The possibility of exploiting the electrocatalytic nature of silver in electrocarboxy...
