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.

Resisting pathways for decomposition followed by palladium complexes of monodentate ligands is one characteristic of the highly reactive but long-lived catalyst generated from the Josiphos ligand L and palladium. It catalyzes under mild conditions the coupling of primary amines with chloropyridines and chloroarenes in high yield with low catalyst loadings (see scheme).

The present invention provides a method for the preparation of a wide range of primary arylamines. The arylamines are prepared in two efficient, straightforward transformations: 1) an activated aryl group and an imine group are combined, in the presence o
