摘要：

The reaction of [Ni(dippe)](2)(mu-H)(2) with a series of fluoroaromatic imines affords nickel(0) complexes of the type [(dippe)Ni(eta(2)-C, N)PhHC=NR ' Ph], dippe = 1,2-bis(diisopropylphosphine)ethane. Solution NMR experiments as well as X-ray diffraction studies confirmed the pi-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 degrees C. (c) 2007 Elsevier B.V. All rights reserved.
