i-Pr3 reacted with the olefiniridium(I) precursor in C7H8/EtOH to yield the carbonyl complexes (i-Pr3P)2H2Ir-μ-Cl2Ir(CO)(PPri3)2 (IV) and IrCl(CO)(PPi3)2 (IVa), no cyclometallated product being detected. The stereochemistries of the complexes were deduced from IR, 1H, 31P, and 13C NMR data. The crystal structures of IIIa and IVa were also determined.
