The complex (Ph3P)Ni(PhNCNPh) (II) is formed from (Ph3P)2Ni(PhNCNPh) (I) in toluene at 60 deg C.II can also be prepared directly from (COD)2Ni, Ph3P and PhNCNPh (45percent yield). (COD)2Ni reacts with diarylcarbodiimides in THF to give (ArNCNAr)3Ni(THF) (VIII).The structure of VIIIa (Ar = phenyl) has been determined by X-ray crystallography.The molecule is shown to contain a <3.3.0>nickela bicyclic group in which the carbodiimide molecules are linked to form a 2,5,8-h3-carbene ligand.Some properties and reactions of II and VIII are described.
