[0139] Under argon atmosphere, tris(3-sulfonatophenyl)phosphine hydrate sodium salt (c) (42.6 mg, 0.075 mmol) and acetylacetonato iridium(1,5-cyclooctadiene) (10.0 mg, 0.025 mmol) were placed in a Schlenk flask. One-half milliliters of a degassed aqueous formic acid solution (98 vol %) was added thereto with a syringe, and the flask was tightly sealed, followed by stirring the resulting mixture at 60 C. for 1 hour. Thereafter, the aqueous formic acid solution was removed under reduced pressure, and the resultant was washed with ethanol, to obtain the iridium hydride complex C as white powder (46.6 mg). Spectroscopic Data of the Iridium Hydride Complex C: [0140] 1H NMR (D2O), delta: 6.97-8.00 (m, 24H), [fac: -10.64 (t, JH-P=18.4 Hz, 1H), -11.83 (ddd, JH-P=102.7, 20.4 Hz, JH-H=4.8 Hz, 2H)]
As the paragraph descriping shows that 63995-70-0 is playing an increasingly important role.
