We report the first practical use of SF6 as a fluorinating reagent in organic synthesis. Photoredoxcatalysis enables the in situ conversion of SF6, an inert gas, into an active fluorinating species by using visiblelight. Under these conditions, deoxyfluorination of allylic alcohols is effected with high chemoselectivity and is tolerant of a wide range of functional groups. Application of the methodology

A resin composition for primer use is described, which contains a copolymer of (I) a radical-polymerizable olefin resin and (c) a monomer copolymerizable with said olefin resin (I) and containing an alkyl (meth)acrylate and/or a fluorine-containing unsaturated monomer as essential ingredients, said radical-polymerizable olefin resin (I) being a product of the reaction of (a) an olefin resin having at least one functional group per molecule with (b) a radical-polymerizable monomer having a functional group reactive to the functional group contained in said olefin resin (a).
A primer composition is also described.

The cycloadditions of nitrileoxides with new and previously studied allylic fluorides were examined. The 1,3-dipolar cycloaddition reactions were also investigated theoretically with density functional theory (B3LYP) based transition-state modelling. The predictions provided reasonable agreement with experiment, indicating that both steric and electronic effects have important influences on the stereoselectivities
