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 NiCl 2 (PMe 3 ) 2 . [PhNi(2‐Ph 2 PC 6 H 4 O)(PMe 3 )], [PhNi(2‐ c Hex 2 PC 6 H 4 O)(PMe 3 )] and [PhNi(2‐Ph 2 P‐4‐MeOC 6 H 3 O)(PMe 3 )], 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‐ c Hex 2 PC 6 H 4 O)(PMe 3 )] in the crystal is reported.
