Palladium-catalyzed peripheral arylation of 5-pyrazolones via enolizable bond protection

Peripheral cross-coupling of the enol form of the 5-pyrazolone scaffold with arylboronic acids promoted by [PdCldppf)] afforded the arylated products in good yields. In this coupling, the protection of the enolizable hydroxyl group of pyrazolone is a prer
