摘要:

A palladium catalyst immobilized on 4-amino-1,2,4-triazole resin was readily prepared and effectively catalyzed the Suzuki reaction of aryl or heteroaryl halides and phenylboronic acid with low palladium amount under aqueous conditions in the absence of phosphine ligand. This catalyst showed reusability in the Suzuki reaction of aryl iodide at least three times.
