Abstract:
de Visser et al. demonstrated theoretically that although vanadium( iv )-oxo complexes are slow oxidants, in the presence of H 2 O 2 they generated a side-on vanadium-peroxo complex, which is an efficient oxidizer. The catalytic activities of vanadium( iv )-oxo complexes are extensively reported in the literature in different ligand backbones, including porphyrin-based ligands. However, similar reports in corrole based ligand systems have not been explored to date. We have reported the synthesis and characterization of two new oxo(corrolato)vanadium( iv ) complexes. Interestingly, we have observed an anionic complex, [V IV O (Corr) 3− ] − . This data is contrary to what was observed earlier by Licoccia et al. We have observed that these newly synthesized oxo(corrolato)vanadium( iv ) complexes are highly efficient oxidizers in the presence of H 2 O 2 and KHCO 3 . The catalytic reaction mixture was thoroughly analyzed, and it was established that an oxo(peroxo)(corrolato)vanadium( v ) complex is the true catalytic intermediate. This is the first report on oxo(corrolato)vanadium( iv ) complexes bearing meso -substitution. In addition to this, these oxo(corrolato)vanadium( iv ) complexes have never been previously investigated from a catalysis point of view.
