Enzymatic synthesis, antioxidant ability and oil-water distribution coefficient of troxerutin fatty acid esters

Grain & Oil Science and Technology, 2019
Troxerutin fatty acid esters were prepared using troxerutin and fatty acid vinyl esters as substrates in pyridine through enzymatic route. The structures of as-prepared compounds were identified by FT-TR, NMR, and ESI-HRMS.

Quantum Cascade Laser-Based Photoacoustic Spectroscopy for Trace Vapor Detection and Molecular Discrimination

Sensors, 2010
We report on the development of a microelectromechanical systems (MEMS)-scale photoacoustic sensor for the detection of trace gases. A mid-infrared quantum cascade laser (QCL) was used to determine detection limits for acetic acid, acetone, 1,4-dioxane ...

Transformation of substituted 2H-pyran-5-carboxylates into 3R*-vinyl-1,2R*-cyclopropanedicarboxylates

, 1998
Substituted alkyl 2H-pyran-5-carboxylates, 1, have been condensed with methyl 2-(triphenylarsoranylidene) ethanoate, 14a, to form substituted 3-vinyl-1,2-cyclopropanedicarboxylates, 15, and, in a number of cases, 2,3-dihydro-3-vinyl-2,4 ...

VINYL CATION FORMATION BY DECOMPOSITION OF VINYL-LEAD TRIACETATES - THE REACTIONS OF VINYLMERCURY AND VINYLTIN COMPOUNDS WITH LEAD-TETRAACETATE

, 1990
Vinylmercury compounds and vinylstannanes undergo rapid metal-metal exchange with lead tetraacetate in chloroform to generate vinyl-lead triacetates, unstable compounds which undergo a thermodynamically favourable reductive elimination of lead(II ...
