GREEN FINE CRYSTALLINE POWDER
Carbonylchlorobis(triphenylphosphine)iridium(I) is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuffs.
Carbonylchlorobis(triphenylphosphine)iridium(I) can be used as a catalyst precursor for homogeneous hydrogenation, decarbonylation of acyl halides, hydrosilylation of olefins, and hydroboration.
In a round-bottomed flask a mixture containing 3.52 g (10 mmol) of IrCl3.3H2O, 13.1 g (50 mmol) of PPh3, 4 mL of aniline, and 150 mL of DMF is heated under nitrogen at reflux for 12 h. After filtering the resulting redbrown solution hot, 300 mL of warm methanol is added rapidly and the mixture stirred. Upon cooling in an ice bath, yellow crystals of Carbonylchlorobis(triphenylphosphine)iridium(I) are collected on a filter and washed with 250 mL of methanol and then with 25 mL of diethyl ether (87-90%).
