Fluoro aromatic imine nickel(0) complexes: Synthesis and structural studies

Abstract

The reaction of [Ni(dippe)] 2(μ-H) 2 with a series of fluoroaromatic imines affords nickel(0) complexes of the type [(dippe)Ni(η 2- C, N)–PhHC NR′Ph], dippe = 1,2-bis(diisopropylphosphine)ethane. Solution NMR experiments as well as X-ray diffraction studies confirmed the π-coordination of the ligand through the C N moiety; the resulting complex found to adopt a distorted tetrahedral geometry around the nickel center. The compounds are thermally stable and decomposition is only observed after long periods of heating above 150 °C.
