摘要: The synthesis of methyl and methoxy substituted benzimidazolin-2-iminato actinide (IV) complexes (1–4), [(Bim2-MeOPh/MeN)AnN″3] [(Bim5-MeDipp/MeN)AnN″3] (An = U, Th; N″ N(SiMe3)2), was performed by the protonolysis metallacycles with respective neutral benzimidazolin-2-imine ligand precursors. Full characterization, including X-ray diffraction studies for all complexes, is reported. Despite high oxophilicity metal centers, these displayed extremely activities in catalytic addition aliphatic aromatic alcohols to carbodiimides, under very mild conditions, providing a facile highly efficient strategy construction carbon–oxygen bonds. Various kinds diols triols can also be used this intermolecular insertion, representing large substrate scope application organoactinide precatalysts.
