We have directly resolved in the present work interfacial composition during and after interactions of a saturated atmosphere oil vapor with soluble surfactant solutions at planar water/air interface for first time. Experiments were conducted on hexane alkyltrimethylammonium bromides sodium dodecyl sulfate to observe balance between cooperativity competition components interface. In all cases, ...

Abstract Several methods are available for elongation of fatty acid acyl chains. The present paper describes adaptation to the field a previously published protocol manganese‐based Wurtz type coupling alkyl bromides. 22‐Bromo‐3( Z ),6( ),9( ),12( ),15( ),18( )‐docosahexaene, easily prepared from 4( ),7( ),10( ),13( ),16( ),19( )‐docosahexaenoic acid, was coupled homologous ω‐bromoesters by stir...

The Ullmann-type coupling reaction of vinyl bromides and imidazoles in ILs at 90-110 degrees C gave the corresponding N-vinylimidazoles in good to excellent yields by using L-proline as the ligand; the double bond geometry of the vinyl bromides was retained under the reaction conditions.

New routes to 1- and 2-adamantyl anion equivalents are described, starting from commercially available 1- and 2-adamantylzinc bromides and employing reducing metals (Mg; Li). Adamantylmagnesium bromides (both 1-AdMgBr and 2-AdMgBr) can reliably be produced via reaction of the corresponding adamantylzinc bromides with excess magnesium metal. Reactions of adamantylzinc bromides with stoichiometic...

A short soak of protein crystals in cryosolution containing bromides or iodides leads to incorporation of these ions into the ordered solvent shell around the protein surface. The halide ions display significant anomalous signal, bromides in the vicinity of the absorption edge at 0.92 A, and iodides at longer wavelengths, e.g., provided by the copper sources. Bromides can, therefore, be used th...
