Grafting of Group‐10 Organometallic Complexes on Silicas: Differences and Similarities, Surprises and Rationale

Surface organometallic chemistry (SOMC) represents a unique synthetic platform for the preparation of model heterogeneous catalysts resembling those broadly applied in industry. SOMC techniques usually rely on grafting tailored molecular precursors onto surface OH groups oxide supports. The development such and understanding their reactivity with supports are therefore crucial well-defined species. While large number early transition metals known, only few examples group 10 metal complexes reported, spite great interest based Pt-group elements. Herein we report family group-10 (Ni, Pd Pt) alkyl complexes, towards partially dehydroxylated SiO 2 yielding supported We studied effect metal, ligand, support mechanism via combined experimental computational approach. Ultimately, showed that at least two pathways possible these compounds, namely protonolysis M-alkyl bond by opening strained siloxane bridges; proportion depending nature its ancillary ligand.
