A novel access to phenylnickel-2-phosphinophenolate trimethylphosphine complexes, which unlike the "P-ylide method" is not limited to P-arylphosphino derivatives, consists of the reaction of 2-phosphinophenols and diphenylnickel-bis(trimethylphosphine), easily prepared from phenyllithium and NiCl2(PMe3)2. [PhNi(2-Ph2PC 6H4O)(PMe3)], [PhNi(2-cHex2PC 6H4O)(PMe3)] and [PhNi(2-Ph2P-4- MeOC6H3O)(PMe3)], the latter two with more basic dialkylphosphino or 4-methoxy substituents, were synthesized and tested in the oligomerization of ethylene. The molecular structure of [PhNi(2-cHex 2PC6H4O)(PMe3)] in the crystal is reported.
