two racemic α‐substituted ketones, namely α‐bromo‐ α‐chloro‐ and α‐chloro‐α‐fluoroacetophenone were investigated to obtain one of the four possible diastereoisomers through a dynamic kinetic process. In the case of the brominated derivative, only the (1R)‐enantiomer was obtained by using ADH‐A, although with moderate diastereomeric excess (>99 % ee, 63 % de), whereas the fluorinated ketone exhibited
