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)(PPh3)Br if the reaction is performed in the presence of Ni(PPh3)(2)Br-2. The Ni(I) complex is a precursor for the catalytic hydrodehalogenation of aryl halides.
