We herein describe a practical direct amination of phenols through a palladium-catalyzed hydrogen-transfer-mediated activation method to synthesize the secondary and tertiary amines. In this conversion, environmentally friendly water and inexpensive ammonium formate were used as solvent and reductant, respectively. A range of amines, including aliphatic amines, aniline, secondary amines, and diamines

efficient iodine anion catalyzed cross-dehydrogenative aromatization of cyclohexenones with amines has been developed under metal-free conditions, which affords aromatic amines in good to excellent yields with a broad substrate scope. Meanwhile, this reaction provides a new method for the construction of C(sp2)–N bonds and also a new strategy for slow generation of oxidants or electrophiles via in situ
