ARTICLE INFO ABSTRACT Keywords: Sarin gas is one of the most lethal nerve agent used in chemical warfare, which its detection is import to prevent Nerve agent sarin a chemical attack and to identify a contamination area. Herein, density functional theory was used to investigate Gas sensor the (12,0) boron nitride nanotube (BNNT) and Si–doped BNNT as possible candidates to sarin detection. The Si- Boron nitride nanotube atoms doped improve the electronic properties of nanotubes by altering the electrostatic potential, HOMO and DFT LUMO energies. Based in the adsorption energies and the conductivity increased to ~33 and 350%, respectively, for Si- and 2Si-BNNT imply that they can be used for sarin detection. -

China § State Key Laboratory of Organometallic Chemistry, Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, 354 Fenglin Road, Shanghai 200032, P. R. China *S Supporting Information ABSTRACT: Manganese(I) complexes bearing a pyridyl-supported pyr- azolyl-imidazolyl ligand efficiently catalyzed the direct β-alkylation of secondary alcohols with primary alcohols under phosphine-free conditions. The β-alkylated secondary alcohols were obtained in moderate to good yields with water formed as the byproduct through a borrowing hydrogen pathway. β-Alkylation of cholesterols was also effectively achieved. The present protocol provides a concise atom-economical method for C−C bond formation from primary and secondary alcohols.

Phosphine Solubilities 281 COHPONENTS: EVALUATOR: P. G. T. Fogg, 1. Phosphine; PH ; [7803-51-2] School of Chemistry, 3 Polytechnic of North London, 2. Organic liquids. Holloway, London N7 8DB United Kingdom. August 1983 CRITICAL EVALUATION: Data obtained by Palmer et aZ (1) and by Devyatykh et aZ (2) have been discussed in detail by Gerrard (3). Mole fraction solubilities calculated from measurements by Palmer et aZ. fall into a consistent pattern with a lower solubility in hydrogen bonded solvents compared with other solvents. There is also an increase in mole fraction solubility with increase in chain length in the case of straight chain alkanes. Solubilities are in the order: in benzene < in cyclohexene < in cyclohexane and in benzene < in toluene < in xylene. The variation of solubility in nitrobenzene, with change in temperature, was measured by both Palmer et aZ. and by Devyatykh et aZ. The ratio V01'PH3/vOl'solvent for a temperature of 295.2 K has been estimated by the compiler from data given by Devyatykh et aZ. to be 8.4. This may be compared with the value of 3.06 given by Palmer et aZ. for a pressure of 1 atm. There is a similar discrepancy between the solubility in liquid paraffin calculated from the data of Devyatykh et aZ and that measured by Palmer. There is also a marked difference between the solubility of phosphine in didecyl phthalate calculated from data given by Devyatykh and that in dibutyl phthalate measured by Palmer. Expressed as V01'PH3/vOl'solvent at 295.7 K the former gives 22.2 and the latter 3.23.
