1,1-Disubstituted styrenes with internal oxygen and nitrogen nucleophiles undergo oxidative fluorocyclization reactions with in situ generated chiral iodine(III)-catalysts. The resulting fluorinated tetrahydrofurans and pyrrolidines contain a tertiary carbon-fluorine stereocenter. Application of a new 1-naphthyllactic acid-based iodine(III)-catalyst allows the control of tertiary carbon-fluorine stereocenters with up to 96% ee. Density functional theory calculations are performed to investigate the details of the mechanism and the factors governing the stereoselectivity of the reaction.

Using various substrates and ligands, we show that electron-deficient, bidentate phosphines are the ligands of choice for palladium-catalyzed arylation of electron-rich olefins. This is in contrast to the reaction of electron-deficient olefins, which bene
Regioselective Heck arylation of unsaturated alcohols by palladium catalysis in ionic liquid

, p. 3591 - 3593 (2008/09/20)
In contrast to almost all of the known examples of Heck arylation of unsaturated alcohols, which yield predominately β-arylated products, arylation under the Pd-DPPP catalysis in ionic liquid leads preferentially to aryl substitution at the α carbon, prov
