rac-2-Phenyl-1-[(2,4,6-triiso­propyl­benzene)­sulfon­yl]aziridine

In the title compound, C₂₃H₃₁NO₂S, the geometry of the triiso­propyl­phenyl group is slightly distorted, with elongated C—C bonds at the ipso-C atom, and an S atom which deviates from the benzene ring plane by 0.228 (2) Å. This distortion is caused by the bulky substituents and, in comparison, an unbent geometry is observed in N-toluene­sulfonyl­aziridine [Zhu et al. (2006). Acta Cryst. E62, o1507–o1508]. π–π inter­actions between adjacent benzene rings [centroid–centroid distance = 3.7928 (11) Å] and are observed.
