Versuchsvorschrift

1,5-cyclooctadiene) Ir[P(RArF)3] (pyridine)+PF6− (2.0 mg) as prepared as in Example 26 (CH3)2C═C(CH3)2 (1.0 mL) is stirred under hydrogen (1 atmosphere) for 6 hours, resulting in the conversion of (CH3)2C═C(CH3)2 to the hydrogenation product, (CH3)2CHCH(CH3)2. The reaction solution is cooled from about 0° C. to about −78° C., resulting in the precipitation of most of the iridium catalyst. The catalyst is separated from the hydrogenation product by dicanting the liquid product from the catalyst. The catalyst can be reused without any loss of activity or selectivity.
