protocol for the Pd‐catalyzed ortho‐arylation of aryl phosphinamide with boronicacid is reported. By using phosphinamide as a new directing group, the reaction proceeds efficiently under mild conditions at 40 °C. Mechanisticstudies reveal that the reaction proceeds via a PdII to Pd0 cycle. The phosphinamide group is also shown to be an effective orienting group for direct CH amination.
