  Chromium Corroles in Four Oxidation States

  摘要：

  We have isolated and characterized chromium complexes of 5,10,15-tris(pentafluorophenyl)corrole [(tpfc)H-3] (1) in four oxidation states: [(tpfc*)CrO][SbCl6] (6): [(tpfc)CrO] (2); [(tpfc)CrO][Cp2Co] W and [(tpfc)Cr(py)(2)] (3). Complex 6 was prepared both by electrochemical and chemical oxidation of 2 its formulation as a (CrO)-O-V ligand-radical species is based on UV-visible absorption as well as EPR measurements. Cobaltocene reduction of 2 gave 4, it was identified as a diamagnetic d(2) (CrO)-O-IV complex from its sharp H-1 NMR spectrum. Reaction of 2 with triphenylphosphine yielded a chromium(III) corrole, [(tpfc)Cr(OPPh3)(2)] (5). Owing to its air sensitivity, 5 could not be isolated in the absence of excess OPPh3. The structure of the Cr-III bis-pyridine complex (3) was determined by X-ray crystallography (Cr-N distances: 1.926-1.952 Angstrom, pyrrole: 2,109, 2.129 Angstrom, pyridine).

  EPR spectra of chromium(V) imido corroles reveal a rich signal at ambient temperature consistent with Cr(V) triple-bond NR (d(1), S = 1/2) containing a localized spin density in the d(xy) orbital, and an anisotropic signal at liquid nitrogen temperature. Our results demonstrate the synthetic utility of organic aryl azides in the preparation of mononuclear metal imido complexes previously considered elusive
