The reaction of NiCl 2 (PMe 3 ) 2 with 2 equivs. of benzylmagnesium chloride in THF at −120 °C affords Ni(η 1 ‐CH 2 C 6 H 5 )(η 3 ‐CH 2 C 6 H 5 )PMe 3 . The formation of this thermally unstable compound is accompanied by bisbenzyl and Ni(0) side products. Single crystal X‐ray analysis confirms the presence of the η 1 ‐benzyl and η 3 ‐benzyl ligands. Reaction of Ni(η 1 ‐CH 2 C 6 H 5 )(η 3 ‐CH 2 C 6 H 5 )PMe 3 with 2‐(diphenylphosphino)benzoic acid and activation with B(C 6 F 5 ) 3 gave the expected product [2‐(diphenylphosphino)benzoate tris(pentafluorophenyl)borate‐κ 2 P,O](η 3 ‐benzyl)nickel.
