Here's looking at the reduction of noninnocent copper corroles via anion induced electron transfer

The synthesis, electrochemical and spectroscopic characterization of five copper triarylcor-roles bearing one, two or three nuno-nitroaryl substituents is reported. Redox potentials and spectroscopic properties of the neutral Cu(II) corrole cation radicals and singly reduced form of the complexes are reported in CH2Cl2 and the ability of the initial noninnocent derivatives to be chemically reduced via anion induced electron transfer (AIET) is explored using cyanide (CN-) or fluoride (F-) anions in the form of tetra - n-butylammonium salts. UV-visible spectra of the singly reduced corroles and the species generated after addition of CN- or F- to solutions of the neutral compounds are identical, thus confirming the AIET event in these systems. This result. when combined with the facile electrochemical reduction, provides strong indirect evidence for the presence of noninnocence in these systems.

Automated summary

This study reports the synthesis, electrochemical and spectroscopic characterization of copper triarylcor-roles with varying numbers of nuno-nitroaryl substituents. The ability of these derivatives to be chemically reduced via anion induced electron transfer (AIET) using cyanide or fluoride anions was explored. UV-visible spectra of the reduced corroles and species generated after the addition of CN- or F- were identical, confirming the occurrence of AIET event in these systems and suggesting the presence of noninnocence.
