Nitro(tetrahenylporphyrinato)cobalt complexes catalyze the oxidation of triphenylphosphine to triphenylphosphine oxide by molecular oxygen. The effects of axial ligands in the nitro cobalt complexes on this oxidation reaction were studied. 4-Cyanopyridine gave the best yield. This result suggests that the more unstable is nitro(tetraphenylporphyrinato)cobalt complex the better the yield obtained.
