The direct magnesiation of highly functionalized aromatics bearing an ester, a nitrile, or a ketone can be readily performed by using an OBoc as a directing group and TMPMgCl-LiCl as a base. It allows, for example, the preparation of a meta-magnesiated benzophenone in > 95%. After quenching, highly functionalized and substituted benzenes are obtained.
