Facile thermally-induced cluster oxidations in metallaborane chemistry: arachno→nido→closo reaction sequences exhibited by iridanonaboranes and iridadecaboranes, and the stabilization of the iridium(V) oxidation state

Abstract

Iridanonaboranes and iridadecaboranes which have adjacent open-face bridging H atoms and terminal Ir–H atoms readily lose H₂ in formal cluster oxidations which involve stable isolable iridium (V) species.
