2-Bromo-1,3-bis-(4-chloro-phen-yl)prop-2-en-1-one
Abstract:
In the title compound, C(15)H(9)BrCl(2)O, the two benzene rings are twisted from each other with a dihedral angle of 47.33 (8)°. The crystal structure is stabilized by aromatic π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.680 (2) Å], and by weak inter-molecular C-H⋯O and C-H⋯Cl inter-actions. Additionally, the crystal structure exhibits a short intra-molecular C-H⋯Br contact (H⋯Br = 2.69 Å).

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
