Abstract
The ambiphilic redox behavior of bis-phosphonio-isophosphindolide ions is d iscussed. Oxidation occurs site-selectively at the endocyclic two coordinat e phosphorus to give lambda(5)-isophosphindolide cations, while reduction p roceeds, depending on the reducing agent, under conversion of phosphonium i nto phosphine or phosphanide centers.
