SPECTROPHOTOMETRIC EVIDENCE FOR THE FORMATION OF A SUPEROXIDE ADDUCT OF CHROMIUM (III) TETRAPHENYLPORPHYRIN COMPLEX

Abstract

This is the first report of the reaction of the superoxide ion (O₂^-) with chloro-5, 10, 15, 20-tetraphenylporphyrinatochromium (III), Cr (III) (TPP) Cl, in dimethyl sulfoxide (DMSO) to give the superoxide adduct Cr (III) (TPP) (O₂^-) Cl.
