Oxidative addition of CCN bond to nickel(0) complex: Synthesis and crystal structures of Ni(CN)(o-C6H4CN) (bpy) and Ni(CN) (p-C6H4CN) (bpy)
摘要:
Reactions of phthalonitrile and terephthalonitrile with Ni(cod)(bpy) in a THF solution at room temperature lead to oxidative addition of the C-CN bond to give square-planar Ni(CN)(o-C6H4CN)(bpy) (3) and Ni(CN)(p-C6H4CN)(bpy) (4) respectively. Data from elemental analysis, as well as their IR and NMR spectra, agree with the structures. Crystal structures of the complexes 3 and 4 have been determined by X-ray crystallography.
