Palladium(0)-Catalyzed Intermolecular Arylative Dearomatization of β-Naphthols

The first Pd0‐catalyzed intermolecular arylative dearomatization of β‐naphthols with aryl halides is described. It was found that Q‐Phos could facilitate the palladium‐catalyzed cross‐coupling‐type dearomatization of β‐naphthols, while avoiding O‐arylation, to construct 2‐naphthalenones in excellent yields and with high chemoselectivity. 2‐Naphthalenones made easy: Pd0‐catalyzed intermolecular arylative dearomatization of β‐naphthols with aryl halides is described.
