Preparation of Nickel Complexes with η2-Coordinated Fluorinated Ketones from Dialkylnickel Complexes
Reactions of hexafluoroacetone and 2,2,2-trifluoroacetophenone with dialkylnickel complexes cause extrusion of alkyl ligands to give nickel complexes having an η2-coordinated ketone and an auxiliary ligand such as bpy (2,2'-bipyridine) or dpe (
