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...

Description
Summary: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. A bulky 6-membered ring N-heterocyclic carbene gives new C-H activated and low-coordinate complexes of nickel.
