the best radical initiator. We also found that water exerts a relevant solvent effect on the rates of perfluoroalkyl radical additions onto double bonds and the H atom abstraction from the silane. Our account provides a versatile and convenient method to achieve perfluoroalkylation reactions of alkenes in water to render perfluoroalkylated alkanes as key intermediates in the synthesis of fluorophors and

The present invention relates to a fluorine-bridged associate consisting of an oligomer or polymer containing fluorine radicals which are bonded to the oligomer or polymer backbone, and up to three types of functional units in the backbone which differ with respect to function and are selected from the group consisting of a hole-transport and/or hole-injection unit, an electron-transport and/or electron-injection unit and an emitter unit, and one to three types of compounds containing a fluorine radical which differ with respect to function and are selected from a hole-transport and/or hole-injection unit, an electron-transport and/or electron-injection unit and an emitter unit, and to an opto-electronic device in which the fluorine-bridged associate is employed.

Efficient Access to Perfluoroalkylated Aryl Compounds by Heck Reaction
been achieved by Heck reactionbetween perfluoroalkenes and arenediazonium salts, catalysed by palladium acetate. Subsequent transition metalcatalysed hydrogenation of the doublebond afforded a large variety of aromatic compounds bearing an affinity for fluorous solvents.
