Fluorous dimethyl sulfide: a convenient, odorless, recyclable borane carrier.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

Borane gas and 2-(perfluorooctyl)ethyl methyl sulfide form a solid comprised of an approximately 1:1 mixture (fluorous BMS) of sulfide and the corresponding sulfide-borane. Fluorous BMS permits hydroboration of alkenes in a dichloromethane/perfluorinated hydrocarbon mixture with subsequent recycling

A versatile method for measuring the partition coefficients of volatile analytes with an aqueous pseudophase using headspace gas chromatography is reported. A "three-phase" model accounts for all equilibria present in the system, including the partitioning of the analyte in the gas and aqueous

Synthesis of 9-oxononanoyl cholesterol by ozonization.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

A new route for the preparation of 9-oxononanoyl cholesterol (5) and its stable dimethylacetal (4) is described. The core aldehyde 5 is one of the major products formed during lipid peroxidation. The synthesis starts with the ozonization of oleic acid in methanol and further reduction with dimethyl

Trifluoroacetic anhydride-catalyzed oxidation of isonitriles by DMSO: a rapid, convenient synthesis of isocyanates.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

A smooth and efficient oxidation of isonitriles to isocyanates by sulfoxides is catalyzed by trifluoroacetic anhydride. With use of DMSO as the oxidant and 5 mol·% TFAA (dichloromethane, -60 to 0 °C), the process is complete in a few minutes, forming dimethyl sulfide as the only byproduct. The newly

Odor composition analysis and odor indicator selection during sewage sludge composting.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

On the basis of total temperature increase, normal dehydration, and maturity, the odor compositions of surface and internal piles in a well-run sewage sludge compost plant were analyzed using gas chromatography-mass spectrometry with a liquid nitrogen cooling system and a portable odor detector.

Identification of impact odorants in Bordeaux red grape juice, in the commercial yeast used for its fermentation, and in the produced wine.
