Abstract

In this paper, we have shown that the [RuCl2 (p-cymene)] 2 complex associated with simple hemisalen ligands is able to racemize (S)-1-phenylethanol. The influence on the racemization process of the ligand's structure as well as the nature of a co-catalyst have been evaluated and optimized. This [RuCl2 (p-cymene)] 2/Ligand/TEMPO racemization system was then associated with the Candida Antarctica B lipase in order to carry out ...
