Versuchsvorschrift

12.2 mg (2×10-5 moles) of [Ir(PPEI)COD]+ClO4- (+) were suspended in 50 ml of isopropanol and oxidized with air for 4 hours. The resulting yellow solution was then degasified at reflux for 20 minutes in a nitrogen flow and successively treated with 4.4 ml of a deaerated isopropanol solution of KOH (4 mg of KOH), effecting a preliminary reduction for 30 minutes at reflux in N2. 3.0 ml of deaerated isobutyrophenone was then added to the solution. After 120 minutes a conversion to phenylisopropylcarbinol (+) of 92.1% with an e.e. of 13% was obtained. Ratios:
