Abstract

An esterification of primary benzylic C-H bonds with carboxylic acids using di-tert-butyl peroxide as an oxidant is catalyzed by novel ionic iron(III) complexes containing an imidazolinium cation. The reaction offers a broad generality and tolerates sterically hindered starting materials.
