Abstract:
Reaction of the bulky 6-membered N-heterocyclic carbene 6-Mes with Ni(cod)(2) gives a C-H activated 6-Mes nickel(II) complex, but the novel three-coordinate Ni(I) species Ni(6-Mes)(PPh(3))Br if the reaction is performed in the presence of Ni(PPh(3))(2)Br(2). The Ni(I) complex is a precursor for the catalytic hydrodehalogenation of aryl halides.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
