Metal halides with low-dimensional molecular structures are the rising stars in horizon of functional materials research. Among them, 1D metal halide hybrids very promising for future optoelectronic applications because their unusual photophysical properties resulting from strong quantum confinement. In past few years, besides lead-based hybrids, research has been extended to lead-free organic ...

The nitrite ® nitro isomerization in nitritopentaamine cobalt (III) halides has been known. In this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (III) halides, is reported. The rate of isomerization is decreased by increasing the size of the counter ions. This decrease is explained on the...

Phytoplankton (microalgae), seaweeds (macroalgae), higher plants and fungi produce halomethanes. Algae and fungi produce both methyl halides and polyhalomethanes, whereas plants are known to produce only methyl halides. Why these organisms produce halomethanes is a question frequently asked by chemists and biologists. This question implies that halomethanes have a function and have a selective ...

The nickel-catalyzed cross-coupling of aryl halides with alkyl radicals derived from alkyl halides has recently been extended to couplings with carbon radicals generated by a co-catalyst. In this study, a new cocatalyst, cobalt phthalocyanine (Co(Pc)), is introduced and demonstrated to be effective for coupling substrates not prone to homolysis. This is because Co(Pc) reacts with electrophiles ...

A transition-metal-free method has been developed for the boryl substitution of functionalized aryl-, heteroaryland alkenyl halides with a silylborane in the presence of an alkali-metal alkoxide. The basemediated boryl substitution of organohalides with a silylborane was recently reported to provide the corresponding borylated products in good to high yields, and exhibit good functional group c...

Reactions of O,O'-dialkyl thiophosphoric acids with alkyl halides, in the presence of a base, provide a direct synthetic route to phosphorothioates via O,O'-dialkyl thiophosphate anion formation. Studies on the reaction of ambident nucleophile ammonium O,O'-diethyl thiophosphate with benzyl halides and tosylate in different solvents show that only S-alkylation is obtained. Reaction of this ambi...

A transition-metal-free method has been developed for the boryl substitution of functionalized aryl-, heteroaryl- and alkenyl halides with a silylborane in the presence of an alkali-metal alkoxide. The base-mediated boryl substitution of organohalides with a silylborane was recently reported to provide the corresponding borylated products in good to high yields, and exhibit good functional grou...

A variety of benzyl halides were converted to the corresponding aldehydes/ketones in respectable yields by IBX in DMSO at 65 C. The bromohydrin reaction of olefins using NBS–H2O in DMSO can be nicely adapted to IBX-mediated oxidation of benzyl halides in such a way that olefins are converted to the corresponding 1,2-diketones in good isolated yields in one-pot. 2006 Elsevier Ltd.

Gold(I) halides, including AuCl and AuBr, were employed for the first time as precursors in the synthesis of Au nanoparticles. The synthesis was accomplished by dissolving Au(I) halides in chloroform in the presence of alkylamines, followed by decomposition at 60 degrees C. The relative low stability of the Au(I) halides and there derivatives eliminated the need for a reducing agent, which is u...
