Abstract: In the title compound, C₂₈H₂₀NO₃P, the five-membered maleimide ring is almost planar. The interplanar angles between the maleimide ring and the three P-bound phenyl rings are 70.6 (2), 60.4 (2) and 54.68 (18)°, while the dihedral angle between the maleimide ring and the N-bound phenyl group is 55.43 (19)°.
