Abstract

The oxidation of chloro-5,10,15,20-tetraphenylporphyrinatochromium(III) with iodosylbenzene proceeds with oxygen transfer to chromium and two-electron oxidation of the metal to give a chromium(V) porphyrinate complex; the e.s.r. spectra of this complex, its ¹⁷O-derivative, and its t-butylamine adduct show strong electron hyperfine interactions with the metal nucleus and the metal ligands and indicate a metal-centred radical as expected for chromium (V).
