Preparation of Nickel Complexes with η2-Coordinated Fluorinated Ketones from Dialkylnickel Complexes

Abstract

Reactions of hexafluoroacetone and 2,2,2-trifluoroacetophenone with dialkylnickel complexes cause extrusion of the alkyl ligands to give nickel complexes having an η2-coordinated ketone and an auxiliary ligand such as bpy (2,2′-bipyridine) or dpe (1,2-bis(diphenylphosphino)ethane).
