There is, in general, a need to find new uses for overproduced and underutilized early lanthanides, and viable organometallic starting materials for synthesis, surface deposition, and catalysis could help solve that problem. Traditionally, preparation of monomeric organolanthanides containing only one type of ligand (so called homoleptic compounds) have been plagued with synthetic difficulties and challenging characterization due to paramagnetic products, salt and solvent coordination, and temperature sensitive products.

The approach we develop, based on the inclusion of β-SiH groups in the alkyl ligand, overcomes

these challenges, and our strategy will make the early organolanthanides species available for new

synthetic, materials, and catalytic applications. We have synthesized compounds supported by

Ph ligand, and our work includes detailed spectroscopic and structural

characterization of the series, which is important and useful for understanding reactivity properties

of heteroleptic or surface grafted derivatives in catalytic or materials applications. Then, selected

applications the compounds as catalysts for C–O bond cleavage via hydroboration, Si–C bond

formation via hydrosilylation, and C–C bond formation in polymerizations will be presented.
