Abstract: | A novel activated prochiral ketoimine, (E)‐acetophenone O‐diphenylphosphoryl oxime, C20H18NO2P, with an electron‐withdrawing substituent on the imine N atom similar to other prochiral ketoimines, has been synthesized and the X‐ray crystal stucture determined. The molecules pack together in the solid state via weak intermolecular C—H...O interactions and both face‐to‐face and edge‐to‐face π‐stacking interactions. |
