The preparation and X‐ray structural characterization of aliphatic amino iodane (III) reagents has been realized. These new reagents could be used for the Cu‐catalyzed directed electrophilic amination of aryl amines.
The first example of nickel(II)-catalyzed site-selective C–H bond trifluoromethylation of arylamine in water is established. In this transformation, a coordinatingactivation strategy is performed by the utilization of picolinamide as a directing group, and target products are obtained in moderate to good yields. In addition, the catalyst-in-water system can be reutilized eight times with a slight
