  Nickel-Catalyzed Reductive Cyclization of Alkyl Dihalides

  摘要：

  The reductive coupling protocol to intra-molecular cyclization of dihaloalkanes is presented. It leads to five- and six-membered rings, with the former being more efficient. The incorporation of secondary alkyl halides generally promotes coupling, efficiency. To the best of our know ledge this is the first catalytic ring closure reaction arising form dihaloalkanes under chemical reductive conditions.

  utilizing selectively deuterated dihydroaromatic compounds, which were generated by cobalt catalysis. The reaction was initiated by catalytic amounts of BF3·Et2O by abstracting hydride or deuteride ions from the respective dihydroaromatic reducing agents and led to a highly regioselective incorporation of deuterium and hydrogen at the desired positions of the starting material.

  A simple protocol for the hydroarylation of olefins to yield diarylmethine products is described. A Friedel–Crafts-type synthetic strategy allows direct access to biorelevant products in high atom efficiency. A combination of substoichiometric amounts of TMSCl and ZnBr2 promotes a rapid hydroarylation process at ambient temperature. The method is high yielding and is amenable to scale-up protocols

  Halide-bridged 1- and 2-methylnaphthyl palladium dimers are presented as convenient, yet highly efficient palladium sources for cross-coupling catalysis. The bench-stable complexes smoothly react with various ligands yielding monoligated palladium precatalysts. These display record-setting activity in various catalytic reactions, clearly beyond that achievable by ligand screening alone.

  This work describes Ni-catalyzed cross-electrophile coupling of benzyl chloroformate derivatives with aryl iodides that generates a wide range of diaryl methane products. The mild reaction conditions merit the C–O bond radical fragmentation of benzyl chloroformates via halide abstraction or a single electron reduction by a Ni catalyst. This work offers a new substrate type for cross-electrophile couplings
