been utilized to elucidate the mechanism of alkene hydrogenation by pincer-type [P2Si]Rh catalysts. Although [P2Si]Rh interacts with H2 to afford a dihydrogen σ-complex rather than a dihydride (seemingly an indication of facile reductiveelimination from Rh(III)), alkane release occurs by competitive σ-bond metathesis (bimolecular) and reductiveelimination (unimolecular) pathways. This unusual behavior

Ir silyl pincer complexes insert into the N-H bonds of anilines and ammonia under mild conditions to form isotable [Cy-PSiP]Ir(H)(NHR) complexes that are resistant to N-H bond reductive elimination at room temperature, even in the presence of arenes, alkenes, and phosphines.
