Ligand Rearrangement and Hemilability in R hodium(I) and Iridium(I) Complexes Bearing Terphenyl Phosphines

We describe the synthesis of a series of cationic rhodium(I) and iridium(I) compounds stabilized by sterically demanding phosphines that contain a terphenyl substituent, PMe 2 Ar’ (Ar’ = 2,6-diarylphenyl radical). Salt metathesis of metal precursors [MCl(COD)(PMe 2 Ar’)] (M = Rh, Ir; COD = cycloocta...
