A study of a range of aromatic mols. was studied electrochem. to determine what makes an effective reducing mediator. With the aim of developing a better understanding of electron transfers (ETs) mediated from Li in functional group reduction, single ET reactions are reported. Typical reaction conditions involved the use of aromatic mediators such as naphthalene, anthracene, 4,4′-di-tert-butyl-1,1′-biphenyl (DBB) with Li metal in THF at -78°. The results of these experiments showed that some mediators were more effective reducing reagents than others. Cryoelectrochem. procedures are used to mimic the conditions of the SET (single electron transfer) reactions to study the exact nature and role of the mediator formed upon ET. Electrogenerated and stabilized radical anions of anthracene at -78° mediate the reduction of organic substrates, whereas the more reactive dianion is quickly protonated and therefore unable to act as an ET reagent; direct electrochem. reduction of the sulfide, Ph 3-phenylpropyl sulfide (RSPh) gives the thiol, thiophenol, and propylbenzene whereas mediated reduction gives the dimer, di-Ph disulfide and Pr benzene. The possibility to selectively reduce a substrate with either a single electron or with 2 electrons is possible by using either the radical anion (mediated) or via the direct electroreduction DBB and naphthalene (both single electron accepting species only) are the most effective reducing reagents. Anthracene and other 2-electron accepting species only showed effective reducing ability when a stoichiometric amount of Li was used therefore preventing the over-reduction to the dianion.
