For the π-bridged multi-PDI derivatives, intramolecular electron transfer is dictated by the super-exchange mechanism and can be greatly tuned by the π-bridge modes.

Catalyst Complex

The homogeneous catalysis of phenylmethanethiol autoxidation ���������������������� 2PhCH2SH+O2 → PhCH2SSCH2Ph+H2O2 by [Co(mnt)2]22- (mnt, doubly deprotonated dimercaptomaleonitrile) in acetonitrile solution buffered with excess PhMe2N and PhMe2NH+ClO4- at 18.0�C is described. Effective catalysis occurs in this medium, with catalyst complex decomposition less than 1 mole % of the turnover. Spectrophotometric and oxygen-consumption kinetic data indicate that the mechanism involves initial coordination of the thiolate to [Co(mnt)2]- to form an intermediate which then, with Bronsted acid assistance, interacts with oxygen to form a second intermediate, which dissociates to products and regenerates [Co(mnt)2]22-. It is concluded that the role of the catalyst is to sequentially coordinate and activate the reactants and facilitate intramolecular electron transfer from thiolate to oxygen, without itself undergoing reduction or oxidation or dithiolene ligand substitution.
