The hydrodehalogenation of a series of aryl, alkyl, allyl, and benzyl chlorides, bromides, and iodides has been carried out efficiently using nickel boride in methanol at ambient temperature, leading to the corresponding products resulting from hydrogen/halogen exchange.

    We have studied the molecular orbitals of ruthenium halides, in order to study the extent of contribution of 4d, 5s and 5p orbitals in the formation of molecular orbitals. The 3D modeling and geometry optimization of the ruthenium halides have been done by CAChe software using molecular...

    Tris(2-hydroxyphenyl)methane derivatives (1) displayed excellent selectivity for chloride (Cl-), in comparison with bromide (Br-), iodide (I-) and nitrate (NO3 -) ions. This selectivity is attributed to the fit size and shape of chloride, which favor the formation of a stable host-guest complex...

    A new method has been devised to enable the determination of halide anions by isotachophoresis. This method uses an electrolyte system that employs indium(III) as a counter-ion to manipulate the effective mobilities of sample species by means of complexation reactions. This new procedure...

    The Doppler profiles of the hydrogen atom photofragments from the photodissociation of HCl and HBr at 157 and 243 nm are observed to determine the symmetries of the photoexcited states by using a resonance enhanced multiphoton ionization technique. The phototransitions are perpendicular for HCl...

    Although reactive halogen species (X*=X•, •X2-, X2 and HOX, where X=Br, Cl, or I) are important environmental oxidants, relatively little is known about their kinetics in condensed phases such as seawater and sea-salt particles. Here we describe a new technique to determine reactive...

    The relative rate constants were determined, and the absolute rate constants were estimated, for halogen transfer from N,N-dihaloarenesulfonamides, (dichloroiodo)arenes, benzyl bromides, and arenesulfonyl chlorides to cyclohexyl radical and from N,N-dihaloarenesulfonamides to benzyl radical....

    Time resolved resonance fluorescence detection of O(3P) and H(2S) has been employed in conjunction with pulsed laser photolysis of O3/HX/He mixtures to determine absolute rate coefficients and product yields for reactions of O(1D) with HCl(1) and HBr(2) at 297 K. Total rate coefficients for...

    A strict approach to determine the adiabatic compressibility of a solvent at constant entropy of the solution is developed. It is shown that the apparent adiabatic compressibility of a solute is not strictly equal to the pressure derivative of the apparent molar volume of a solute at constant...
