Benzyltriphenylphosphonium Dichromate as a Mild Reagent for Oxidation of Thiol and Sulfides
Abstract:
Oxidation of thiols and sulfides under non-aqueous and aprotic conditions uses benzyltriphenylphosphonium dichromate (1, PhCH2PPh3)2 Cr2O7) which is very easily prepared by mixing an aqueous solution of benzyltriphenylphosphonium chloride with CrO3 in 3N HC
Construction, Characterization and Biological Activity of Chiral and Thermally Stable Nanostructured Poly(Ester-Imide)s as Tyrosine-Containing Pseudo-Poly(Amino Acid)
Abstract
In this paper we studied the synthesis of biodegradable optically active poly(ester-imide)s containing different amino acid residues in the main chain.
Nanocomposites of Poly(vinyl alcohol) Reinforced with Chemically Modified AL2O3
Abstract
The surface of α-alumina (Al2O3) nanoparticles was first modified with γ-aminopropyltriethoxy silane as a coupling agent.
Straightforward and green method for the synthesis of nanostructure poly(amide-imide)s-containing benzimidazole and amino acid moieties by microwave irradiation
Abstract
Owing to unique advantages such as shorter reaction times, higher yields, limited generation of by-products, and relatively easy scale-up without detrimental effects, microwave (MW)-assisted polymer synthesis has become an interesting sy
The synergetic effect of chiral organoclay and surface modified-Al2O3 nanoparticles on thermal and physical properties of poly(vinyl alcohol) based nanocomposite films
Abstract
In the present investigation, poly(vinyl alcohol) (PVA)/organoclay/surface modified Al2O3 nanocomposites (POANC)s of different compositions were prepared by solution intercalation method.
