Oxygenation of Saturated Hydrocarbyl Groups in the Dinuclear Ni(III) Bis(μ-oxo) Complexes with the Hydrotris(pyrazolyl)borate Ligands TpR (R = Me3 and Pri2)

Intramolecular oxygenation of the Me and Pri substituents of TpR to give the carboxylate (–CO2−) and enolate (–CMe=CHO−) groups, respectively, is mediated by the Ni(III)2-bis(μ-oxo) complexes in the presence of an excess amount of H2O2.
