    • Figure 10 shows the conversion and enantiomeric excess for the reduction of tetralone with borane in the presence of a polysiloxane bound oxazaborolidine in detail. Up to this point of 200 residence times 321 turnovers were obtained. The turnover number was calculated with the simplifying assumption that no catalyst leaching occurred. The reaction was started with 100 mol % of catalyst. After 143 residence times the tetralone concentration was doubled. The tetralone concentration was increased again after 168 residence times to an amount of 25 mol % catalyst, again excluding catalyst loss by leaching or by decomposition of the catalyst.

    • note
    • It can be calculated that an amount of 1.2 mol % of catalyst is necessary to run the reduction of tetralone with borane in an optimal way in respect to conversion and enantiomeric excess.
