Cyclopalladated complexes of 2-phenylaniline and their catalytic activity in Suzuki and Heck reactions under mild conditions

A series of palladium complexes bearing monodentate and bidentate ligands were applied in the Suzuki reaction of aryl halides and the Heck reaction of styrene with phenylboronic acid. The complexes were found to be effective catalysts for these reactions affording the cross-coupled products in moderate to excellent yields.

This Letter describes the applications of NC-palladacycle compounds with mono and bidentate ligands in Suzuki and Heck reactions. The results show these complexes are more efficient in Suzuki reactions.
