Copper-Catalyzed Hydroxylation of (Hetero)aryl Halides under Mild Conditions.

Journal of the American Chemical Society, 2016
The combination of Cu(acac)2 and N,N'-bis(4-hydroxyl-2,6-dimethylphenyl)oxalamide (BHMPO) provides a powerful catalytic system for hydroxylation of (hetero)aryl halides.

Ruthenium-Catalyzed C-H Hydroxylation in Aqueous Acid Enables Selective Functionalization of Amine Derivatives.

Journal of the American Chemical Society, 2017
The identification, optimization, and evaluation of a new catalytic protocol for sp3 C-H hydroxylation is described. Reactions are performed in aqueous acid using a bis(bipyridine)Ru catalyst to enable oxidation of substrates possessing basic amine ...

Microsomal hydroxylation of decane

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1969
Abstract 1. 1. Aliphatic hydrocarbons (hexane, octane and decane) were oxidized in the microsomes from the livers of mouse, rat, rabbit, beef, pigeon and chick embryo. 2. 2. The oxidation of decane by mouse liver microsomes required NADPH and O 2 .

Fe-Based Metal–Organic Frameworks for Highly Selective Photocatalytic Benzene Hydroxylation to Phenol

, 2015
Phenol is one of the most important chemicals in industry. One-step selective benzene hydroxylation is an attractive yet challenging method for phenol production, especially when such a reaction can be driven by solar energy.

Estrogen Hydroxylation in Osteoporosis

2007
Estrogen is metabolized predominantly via two competing pathways, the 2-hydroxyl (nonestrogenic) and the 16alpha-hydroxyl (estrogenic) pathways. Studies have indicated that these pathways are important determinants of bone mineral density (BMD) in postmenopausal women.

The microbiological hydroxylation of levonorgestrel

Natural Product Research, 2006
The microbial transformation of levonorgestrel (1) by Cunningham elegans resulted in the formation of five hydroxylated metabolites, 13-ethyl-10beta, 17beta-dihydroxy-18,19-dinor-17alpha-pregn-4-en-20-yn-3-one(2), 13-ethyl-6beta,17beta-dihydroxy-18,19-dinor-17alpha-pregn-4-en-20-yn-3-one (3) 13-ethyl 6beta, 10beta, 17beta-trihydroxy-18,19-dinor-17alpha-

ReaxFF Molecular Dynamics Simulations of Hydroxylation Kinetics for Amorphous and Nano-Silica Structure, and Its Relations with Atomic Strain Energy

, 2016
We performed reactive force field molecular dynamics simulation to observe the hydrolysis reactions between water molecules and locally strained SiO2 geometry. We optimized the force field from J. Fogarty et al.

Hydroxylated Kininogens and Kinins

1992
Hydroxyprolyl-3-bradykinin was identified in the digest of purified human high molecular weight (H) kininogen with plasma kallikrein. Hydroxyproline was not detected in the heavy and light chains portions of H kininogen, although they include three possible sites for hydroxylation of proline by proline hydroxylase.

Hydroxyl-Radical Footprinting

Cold Spring Harbor Protocols, 2007
INTRODUCTIONThe hydroxyl-radical footprinting methodology has wide applications to studying protein-DNA interactions, as well as structural perturbations (e.g., bending) that occur in DNA during protein binding. Hydroxyl radicals cleave DNA by abstracting a hydrogen atom from C4 of the sugar in the minor groove.

Hydroxylation of the surface of PbS nanocrystals passivated with oleic acid

Science, 2014
Nanoparticle lattices and surfaces The challenge of resolving the details of the surfaces or assemblies of colloidal semiconductor nanoparticles can be overcome if several characterization methods are used (see the Perspective by Boles and Talapin ...
