Syntheses of Organofluorine Compounds by Oxidative Fluorination Reaction.

Defluorination of Organofluorine Sulfur Compounds by Pseudomonas Sp. Strain D2

Little is known of the potential for biodegradation of fluorinated sulfonates. To evaluate this potential, the following model compounds were selected: difluoromethane sulfonate (DFMS), trifluoromethane sulfonate (TFMS), 2,2,2trifluoroethane sulfonate (TES), perfluorooctane sulfonate (PFOS), and 1H,1H,2H,2H-perfluorooctane sulfonate (H-PFOS). A laboratory isolate designated Pseudomonas sp. stra...

Chemo-enzymatic fluorination of unactivated organic compounds.

Fluorination has gained an increasingly important role in drug discovery and development. Here we describe a versatile strategy that combines cytochrome P450-catalyzed oxygenation with deoxofluorination to achieve mono- and polyfluorination of nonreactive sites in a variety of organic scaffolds. This procedure was applied for the rapid identification of fluorinated drug derivatives with enhance...

Mathematical Modeling of Fluorination Reaction of Uranium Dioxide and Evaluation of Existing Gas-Solid Reaction Models

Manganese-catalyzed oxidative benzylic C-H fluorination by fluoride ions.

An efficient protocol for the selective fluorination of benzylic C-H bonds is described. The process is catalyzed by manganese salen complexes and uses nucleophilic fluorine sources, such as triethylamine trihydrofluoride and KF. Reaction rates are sufficiently high (30 min) to allow adoption for the incorporation of (18)F fluoride sources for PET imaging applications.

Syntheses of Soluble GaN Nanocrystals by a Solution-Phase Reaction

A solution phase synthetic method of colloidal GaN nanocrystals at the low temperature has been reported. The syntheses involve the reaction of gallium chloride and lithium nitride in aromatic type solvents mixed surfactants, trioctylphosphine (TOPO) at the temperature below 300 C. The resulting nanocrystals were crystalline and generally spherical with the surfaces passivated by TOPO giving th...
