Selective nickel-catalyzed fluoroalkylations of olefins.

Mild and selective nickel-catalyzed trifluoromethylation and perfluoroalkylation reactions of alkenes were developed to provide fluorinated olefins, including natural products, pharmaceuticals, and variety of synthetic building blocks in good to excellent yields (38 examples). Control experiments, kinetic measurements and in situ EPR studies reveal the importance of radical species and the formation of 1,2-adducts as intermediates.

A general and practical Ni-catalyzed C-H perfluoroalkylation of (hetero)arenes.

A direct perfluoroalkylation of (hetero)arenes using the air- and moisture-stable complex (dppf)Ni(o-tol)Cl was developed (23 examples). The novel procedure allows for the synthesis of various fluorinated products and tolerates sensitive functional groups including aldehydes, free amino groups and several heterocycles.
