    • A catalyst loading of 2mol% on a 1mmol scale corresponds to 20μmol (10-15mg) of the organometallic compound and a further decrease of the catalyst amount would be questionable in terms of reproducibility. Possibilities to increase the amount of substrate are likewise limited because of the relatively high price of enantiomerically pure sec-alcohols required for the racemization studies.
