The selectivefluorination of compounds containing benzylic hydrogen atoms was accomplished by electrolysis in a mixture of 70% HF and 30% pyridine (Olah's reagent) using a square wave alternating current (1.76–2.75 V, 0.02–0.05 Hz) and Pt electrodes. This method can be used in the laboratory to prepare conveniently gram-size quantities of monofluorinated products. An ion radical mechanism has been
The present invention relates to an iridium-based catalyst compound for hydrogenating reducible moieties, especially imines and iminiums, the catalyst compounds being defined by the formulas: where ring B is either itself polycyclic, or ring B together with R is polycyclic. The catalysts of the invention are particularly effective in reductive amination procedures

which involve the in situ generation of the imine or iminium under reductive hydrogenative conditions.

The present invention provides compositions of matter, kits and methods for their use in the treatment of MAP kinase-related conditions and/or HMG-CoA reductase-related conditions. In particular, the invention provides compositions for treating inflammatory and/or cardiovascular conditions in an animal subject by inhibiting p38α MAP kinase and/or HMG-CoA reductase, as well as providing formulations and modes of administering such compositions. The invention further provides methods for the rational design of inhibitors of MAP kinase, HMG-COA reductase, or both for use in the practice of the present invention.

The first palladium-catalyzed direct monofluoromethylation of arylboronic esters to produce monofluoromethyl arenes is reported. The reaction is typically carried out at room temperature within 4 h and has a good functional group tolerance. The monofluoromethylating agent, CH2FI, was readily prepared via a halogen-exchange process.
