Reactivity of a mononuclear iridium(I) species bearing a terminal phosphido fragment embedded in a triphosphorus ligand

Abstract

The first example of an iridium(I) species bearing a terminal phosphido (PR2-) ligand is reported. This stable compound shows well-behaved reactivity toward various electrophiles, owing to its exposed phosphorus lone pair, allowing reversible protonation, selective alkylation, isolation of a phosphidoborane of iridium, and generation of a phosphido-bridged iridium(I)-gold(I) dinuclear species. © 2013 American Chemical Society.
