Palladium-catalyzed direct C–H arylation of ferrocenecarboxamides with aryl halides†
Abstract
A simple and facile protocol for the palladium-catalyzed ortho-arylation of ferrocenecarboxamides with aryl halides was developed with the assistance of the bidentate directing group. The substrate scope could be extended to aryl iodides, bromides and even chlorides, as well as heterocyclic halides, affording diarylated products in moderate to good yields.
