Novel µ-Bridged Heterometallic Heteroleptic Macrocyclic Tetrapyrrole Complexes as a Molecular Platform for Catalysis

Binuclear μ-bridged complexes bearing porphyrin and phthalocyanine ligands and MnIV=C=RuIV, FeIV=C=MnIV, or FeIV=N−MnIII units were prepared and characterized for the first-time. The compounds were identified by UV-Vis, IR and EPR spectroscopy, MALDI TOF mass spectrometry, as well as electrochemical techniques. The potential of the compounds obtained as oxidants for decomposing β-carotene upon exposure to tBuOOH was explored under mild conditions. The key intermediates were demonstrated to be stable and were detected spectrally.
