dc.description.abstractThe synthesis, structure and reactivity of organolanthanide complexes supported by a family of novel bis(phosphinimine)carbazole and bis(phosphinimine)pyrrole pincer ligands is presented. Through the systematic development of the ligand frameworks, rare earth metal species with unique structure and reactivity were encountered. A variety of complexes that exhibited unusual bonding modes were prepared and characterized by single-crystal X-ray diffraction and multinuclear NMR spectroscopy. Modulation of the ligand frameworks allowed for rational manipulation of the steric and electronic environment imparted to the metal. Incorporation of a variety of N-aryl rings (mesityl, phenyl, para-isopropylphenyl and 2-pyrimidine) and PR2 moieties (PPh2, PO2C2H4 and PMe2) into the ligand design led to rare earth complexes that revealed diverse reaction behaviour. In particular, C–H bond activation, sigmatropic alkyl migration and ring opening insertion reactivity were observed. Kinetic and deuterium labeling studies are discussed with respect to the unique reaction mechanisms encountered during the study of these highly reactive organometallic rare earth complexes.en_US
