Stabilization of High-Valent Metals by Corroles: Oxo[tris(pentafluorophenyl)corrolato]chromium(V)
Abstract
The aerobic reaction of Cr(CO)_6 with tris(pentafluorophenyl)corrole (H_3(TpFPC)) in toluene gives the dark red oxochromium(V) compound (TpFPC)Cr(O), which has been characterized by X-ray crystallography, electrochemistry, and EPR spectroscopy. Short Cr−N (1.927−1.943 Å) bonds as well as relatively large ^(14)N and small ^(53)Cr coupling constants suggest that σ(N → Cr) donation is responsible for the unusual stability of chromium(V) in this complex. The Cr^(V/IV) reduction potential (0.11 V vs Ag/AgCl) is 0.65 V below that of oxo(tetramesitylporphinato)chromium(V).
