Resonance Raman Characterization of (Oxoferryl)Tetraphenylporphyrin Formed During Photodisproportionation of (Fe(TPP))(2)O in a Detergent Micelle at Room-Temperature
We report the formation and characterization of (oxoferryl)tetraphenylporphyrin ((TPP)Fe-IV=O) as a result of photodisproportionation of the mu-oxo dimer, (Fe(TPP))(2)O, obtained on solubilization of Fe(TPP)Cl in an aqueous alkaline TX-100 detergent micelle, under 441.6 nm laser excitation at room temperature and at -50 degrees C. The other photoproduct is identified as a five-coordinated, high-spin (5cHS) ferrous complex.
