Electroreduction of (Ph2Sb)2O (1) in THF gives Ph2Sb^-, which can also be obtained by uptake of two electrons on (Ph2Sb)2 (2).Ph2Sb^- reacts with the supporting salt (ⁿBu4NPF6) to yield tributylamine and Ph2Sb(ⁿBu) (3).The electroreduction of 3 and Ph3Sb (4) gives also the anion Ph2Sb^-.There is a considerable influence of the electrode surface on the redox properties of 1-4.Mechanistic aspects are discussed.
