A practical procedure has been developed for the dynamickineticresolution of 1,2-diarylethanols. This procedure employs a highly enantioselective lipase from Pseudomonas stutzeri (trade name, lipase TL) as the resolutioncatalyst and a rutheniumcomplex as the racemizationcatalyst. Sixteen 1,2-diarylethanols have been efficiently resolved to provide their acetyl derivatives with good yields (95-97%)
