Synthesis,Structure and Properties of a Novel Nickel(Ⅱ) Chloride Complex Supported by Phosphine Ligands
摘要
The C-C1 bond of N-（2-chlorophenyl）acetamide （1） was successfully activated by tetrakis（trimethylphosphine）nickel（0）. The four-coordinate nickel（II） chloride complex trans- [（C6H4NHC（=O）Me）Ni（PMe3）2CI] （2） as a C--CI bond activation product was obtained without coordination of the amide group. Phosphonium salt CI[Me3P＋-ortho-C6H4NHC（=O）Me] （3） was isolated by reacting complex 2 as a starting material under 1 bar of CO at room temperature. The molecular and crystal structures of 2 were determined by single-crystal X-ray diffraction.
