Abstract

The preparation of complex polyfunctional organometallic reagents is of pivotal interest in organic synthesis.[1] Recently, functionalized organomagnesium reagents have become accessible through a halogen/magnesium exchange [2] or a directed metalation.[3] During these studies it became apparent that aryl magnesium halides are compatible with important functional groups, such as cyano, nitro, ester, or even keto groups.[4] This observation ...
