title: 1-Allyl-3,3-diphenyl-indolin-2-one.
abstract: In the title compound, C(23)H(19)NO, the oxindole residue is essentially planar and is almost perpendicular to the phenyl rings [dihedral angles = 72.1 (6) and 77.6 (6)°]. The mol-ecular packing is stabilized by C-H⋯O hydrogen bonds and C-H⋯N inter-actions.
