Experimental realization of catalytic CH_4 hydroxylation predicted for an iridium NNC pincer complex, demonstrating thermal, protic, and oxidant stability [PDF]

open access: yes, 2009
A discrete, air, protic, and thermally stable (NNC)Ir(III) pincer complex was synthesized that catalytically activates the CH bond of methane in trifluoroacetic acid; functionalization using NaIO_4 and KIO_3 gives the oxy ...

Stereochemistry of the α-oxidation of 3-methyl-branched fatty acids in rat liver

open access: yesJournal of Lipid Research, 1999
The stereochemistry of the α-oxidation of 3-methyl-branched fatty acids was studied in rat liver. R- and S-3-methylhexadecanoic acid were equally well α-oxidized in intact hepatocytes and homogenates.

Asymmetric Fe–Te Pairs Enhance Peroxymonosulfate Activation via Surface‐Bound Hydroxyl Radicals Pathways

open access: yesAngewandte Chemie International Edition, EarlyView.
An asymmetric Fe–Te dual‐atom pair directs peroxymonosulfate activation toward long‐lived surface‐bound hydroxyl radicals through strong p–d hybridization. The resulting electronic asymmetry enables efficient pharmaceutical degradation and reveals a metal–metalloid pairing strategy for steering reactive oxygen species pathways in advanced oxidation ...
