A task-specific ionic liquid bearing an anhydride moiety was synthesized for the first time in good yield (83%) through a carbodiimide-mediated coupling reaction. The enantiomeric separation of a series of sec-alcohols was performed via enzymatic kinetic resolution, employing an ionic anhydride as acylatingagent and Candidaantarctica Lipase B as a biocatalyst. A fast and efficient recovery of both

Potential acylatingagents containing pendant ionic groups have been screened for the enzymatic kinetic resolution of rac-secondary alcohols in ionic liquids with CAL-B as bio-catalyst. This study has allowed the identification of the 1-methyl-3-alkylimidazolium cation attached to a carboxylate group through a C 10 -alkyl chain as an efficient acylatingagent for this transformation. This strategy
