Abstract:
Grafting Ta(═NtBu)(CH2CMe2Ph)3 onto the surface of silica partially dehydroxylated at 300 °C leads to the formation of the surface imido complex (≡SiO)2Ta(═NtBu)(CH2CMe2Ph) as a major species, which was characterized with EXAFS, 13C CP/MAS NMR, diffuse reflectance FTIR, elemental analyses, and chemical reactivity. The obtained material acts as an efficient heterogeneous catalyst for various oxo/imido heterometathesis transformations: imidation of ketones and DMF with N-sulfinylamines and condensation of N-sulfinylamines into sulfurdiimines and phenyl isocyanate into diphenylcarbodiimide.
