This is advisable, as with the used permethylated cyclodextrin phase, the underivatised phenylethanols show significant tailings. This often makes baseline separations impossible, thus diminishing the accuracy of enantiomer analysis. This drawback is avoided by derivatising the alcohol

1 have shown, that no such reaction occurs even at 25 °C, a second equivalent of α-pinene could theoretically be eliminated at elevated temperatures. We checked this in an experiment, where 2 eq. of acetophenone reacted with 1 eq. of 1 at +64 °C under standard conditions. We found that only 1 eq. acetophenone was consumed in this reaction.
