ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Metal nanoparticles deposited on N-doped carbon materials have emerged as novel catalysts for various organic transformations. In this Minireview, strategies for the synthesis of metal composites on N-doped carbon supports and their state-of-the-art characterization are briefly described. The catalytic application of these fascinating materials in several industrially relevant reactions, including oxidations, hydrogenations, Fischer-Tropsch syntheses, and H2 generation, is also summarized. Furthermore, the effects of nitrogen incorporation on the different catalytic systems are highlighted.
