2‐Pyridinyl/quinolyl‐phenylamino‐quinoline Complexes With CF3 and C2F5 Ligated Ni

Abstract

A new ligand architecture based on quinoline/pyridine attached ortho to the amine functionality on an aniline, which is coupled to another quinoline unit has been prepared. Ligands L1 and L2 have been complexed with CF3 and C2F5 ligated nickel centers. The resulting complexes have been extensively studied by NMR spectroscopy (on 1H, 13C{1H}, and 19F nuclei) and single‐crystal X‐ray crystallography. A poorly defined mixture of complexes obtained from L1 and nickel bis‐trifluoromethyl complex was moderately active in C‐H trifluoromethylation with the Umemoto I reagent.
