WebAccess to homoleptic phosphinine-based coordination compounds of d 6 metals has so far remained elusive. We report here on the preparation and full characterization of the first homoleptic phosphinine–iridium (III) complex, obtained by C–H activation of 2,4,6-triphenylphosphinine with [Ir (acac) 3 ]. WebA novel synthetic method for metallabenzene was developed in which a phosphorus atom in a phosphinine ring is swapped with transition metal fragments. The oxidation of a phosphinine pincer iridium complex by O 2 afforded iridabenzene via exchange of the phosphorus atom and the iridium fragment.
