Anilido-phosphinimines

Anilido-phosphinimines are another group of asymmetric monoanionic bidentate ligands, similar to anilido-imine ligands deriving from aniline-imines 1 (Scheme 19) [51]. Anilido-phosphinimines are obtained by deprotonation of the corresponding... 

Investigation of the catalytic activity of anilido-phosphinimine rare-earth metal complexes was exclusively reported by Cui and coworkers. Various anilido-phosphinimine rare-earth metal complexes were synthesized by deprotonation of aniline-phosphinimines II-A with [Ln(CH2SiMe3)3(THF)2] [53]. Interestingly, the deprotonation of II-A was followed by intramolecular C-H activation of the phenyl group on the phosphine moiety to generate dianionic ligands which coordinated to the metal center in a CA A -tridentate mode. The resulting complexes...
