Palladium-catalysed aminocarbonylation of aryl iodides in the presence of 2-aminobenzimidazole and 2-aminobenzoxazole as N-nucleophile was carried out. Single CO insertion took place, however, instead of the expected carboxamides (C(O)NH) the corresponding N-acyl-imine (C(O)N]C) derivatives were obtained. The structure of the latter compounds can be explained by tautomerization involving the heterocyclic ring. The above structures without amide-NH moieties were proved by methylation at the NH groups of the heterocycle. The resulted mono- and dimethylated benzimidazole derivatives, as well as monomethylated benzoxazole derivatives, like the parent N-acylated compounds, were fully characterised including single crystal X-ray crystallography.
