In methanol, N-benzyl ammonium resorcinarene chloride (Bn-NARCl) crystallizes as a solvate with the benzyl groups oriented in an open flower-like manner parallel to the cation−anion seam. 1,4-Dioxane as guest triggers a “semi-closed” single-molecule capsule with two benzyl “arms” enclosing the guest. The introduction of halogen bond (XB) donor 1,4-diiodoperfluorobutane (1,4-DIOFB) additionally ...

Solution behaviour prevailing in L-Asparagine two aqueous ionic liquid solutions, namely (Benzyl tri–methyl ammonium chloride; Benzyl tri-ethyl chloride) have been studied by investigation of physico-chemical parameters; density, viscosity, refractive index, conductance and surface tension measurement respectively. The nature interactions occurring the solution calculated on basis apparent mola...

The ability to reversibly control protein structure and function with light would offer high spatiotemporal resolution for investigating biological processes. To confer photoresponsiveness on general proteins, we genetically incorporated a set of photoswitchable click amino acids (PSCaas), which contain both a reversible photoswitch and an additional click functional group for further modificat...

We have developed a method to obtain polymer hybrids with control of inorganic content and molecular configuration. Hybrid poly(methyl methacrylate) (PMMA) was obtained via atom transfer radical polymerization (ATRP) initiated by octafunctional cubic silsesquioxanes using CuCl as catalyst. Two different ATRP initiators obtained by attaching specific chemical groups to the cubic silsesquioxane w...

Fifty-three cosmetic products containing one or more of the ingredients N,N-dimethyloctadecylamine oxide, N,N-dimethyloctadecylamine and N-benzyl-N,N-dimethyloctadecylammonium chloride were analysed for N-nitroso-N-methyloctadecylamine by gas chromatography with detection by a Thermal Energy Analyzer. [1-14C]N-Nitroso-N-methyloctadecylamine was used as an internal standard. Eight of 11 products...

In continuation of previous work sensitization experiments have been made with various substances such as urushiol, benzyl chlorides, and acyl chlorides. In the case of a series of substituted benzenes (Cl, NO(2)) a connection between sensitizing capacity and lability of the Cl or NO(2) groups has been shown, indicating the formation of conjugated antigens in the animal. This led to the study o...

Benzyl chloride is economically one of the most important starting materials for a large number of industrial syntheses. Far too much money is now spent to buy and import this valuable product. The production of benzyl chloride has been recognized as one of our national projects and budgeted by the National Iranian Petrochemical Organization in order to economize on the country’s foreign exchan...

The influence of temperature and solvent effects on the reduction and amination mechanisms of iodomethane by lithium N,N-diisopropylaminoborohydride (iPr-LAB) was examined in varying concentrations of THF and dioxane. The reactions of benzyl chloride and trimethylsilyl chloride with iPr-LAB in THF were also studied. The amination of iodomethane is favored over reduction at low and room temperat...

   The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid. Ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea w...
