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(=N tBu)(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.

Grafting the molecular complex (MesN)2Mo(CH2CMe2Ph)2 onto the surface of silica dramatically enhances its catalytic activity in the oxo/imido heterometathesis reaction of N-sulfinylamines with carbonyl compounds.
