Porous silica spheres as indoor air pollutant scavengers [PDF]
, 2010 Porous silica spheres were investigated for their effectiveness in removing typical indoor air pollutants, such as aromatic and carbonyl-containing volatile organic compounds (VOCs), and compared to the commercially available polymer styrene ...

Synthesis and Biological Activity of Novel O-Alkyl Derivatives of Naringenin and Their Oximes
Molecules, 2017 O-Alkyl derivatives of naringenin (1a–10a) were prepared from naringenin using the corresponding alkyl iodides and anhydrous potassium carbonate. The resulting products were used to obtain oximes (1b–10b).

Angewandte Chemie, EarlyView.The vanadium‐dependent haloperoxidase (VHPO) class of enzymes has been shown to catalyze cryptic nitrile oxide generation in an oxidative [3+2] cycloaddition reaction between aldoximes and alkenes to generate isoxazolines. This biotechnology has been applied to a chemoenzymatic sequence starting from aldehydes through in situ condensation with ...

Mixed‐Functionalized Acylgermanes Result in Wavelength‐Controlled Fragmentation
Angewandte Chemie, EarlyView.Selective radical generation from PEG‐acylgermanes is achieved by controlling the used wavelength. Distinct aryl‐carbonyl units undergo wavelength‐dependent α‐cleavage, producing radicals with different reactivities. UV/Vis, TD‐DFT, and photo‐CIDNP spectroscopy confirm that small adjustments in light input directly dictate radical identity and ...

Indole diterpenoid natural products as the inspiration for new synthetic methods and strategies. [PDF]
, 2017 Indole terpenoids comprise a large class of natural products with diverse structural topologies and a broad range of biological activities. Accordingly, indole terpenoids have and continue to serve as attractive targets for chemical synthesis.

Angewandte Chemie, EarlyView.The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

The Separation of Cobalt by Solvent Extraction Using Oxime-Amine Mixture System
Journal of MMIJ, 2017 Extraction behavior of cobalt from sulfate media containing excess manganese by mixtures LIX63 and several amines was investigated. The addition of amines shifted cobalt extraction isotherm to higher pH region in all case.

Improving the mesomorphic behaviour of supramolecular liquid crystals by resonance-assisted hydrogen bonding [PDF]
, 2019 A systematic structure-property relationship study on hydrogen-bonded liquid crystals was performed, revealing the impact of resonance-assisted hydrogen bonds (RAHBs) on the self-assembling behavior of the supramolecular architecture.
