We report the combination of organo-photocatalysis with transition metal (TM) catalysis for directed ortho-hydroxylation of substituted anilides for the synthesis of α-aminophenol derivatives under mild conditions. The developed metallaphotocatalysis utilizes N-pivaloyl as a directing group and phenyl iodine (III) bis (trifluoroacetate)(PIFA) in the combination of the 1, 2, 3, 5-tetrakis (carbazol-9-yl)-4, 6-dicyanobenzene (4CzIPN) photocatalyst and [RuCl2 (p-cymene)] 2 TM catalyst under visible-light irradiation at room temperature. The …
