Ethylene Oligomerization at Coordinatively and Electronically Unsaturated Low-Valent Nickel

Three modes: An iminoferrocenylphosphane ligand stabilizes low‐coordinate and low‐valent nickel in [{[η‐C5H4CHN(C6H5)]Fe[η‐C5H4P(tBu)2]‐N,P}NiICl] (see figure) and similar complexes. The coordination environment is hemilabile as exemplified by three different coordination modes: P,N(σ)‐chelate, P,C...

Description
Summary:	Three modes: An iminoferrocenylphosphane ligand stabilizes low‐coordinate and low‐valent nickel in [{[η‐C5H4CHN(C6H5)]Fe[η‐C5H4P(tBu)2]‐N,P}NiICl] (see figure) and similar complexes. The coordination environment is hemilabile as exemplified by three different coordination modes: P,N(σ)‐chelate, P,CN(π)‐chelate, and P unidentate. These complexes are catalytically active towards ethylene oligomerization.
