(2E)-1-(2-Bromo-phen-yl)-3-(4-chloro-phen-yl)prop-2-en-1-one
Abstract:
In the title compound, C(15)H(10)BrClO, the dihedral angle between the mean planes of the benzene rings in the ortho-bromo- and para-chloro-substituted rings is 70.5 (6)°. The dihedral angles between the mean plane of the prop-2-en-1-one group and the mean planes of the benzene rings in the 4-chloro-phenyl and 2-bromo-phenyl rings are 14.9 (3) and 63.3 (8)°, respectively. In the crystal, inversion dimers linked by pairs of weak C-H⋯O interactions are observed as well as aromatic π-π stacking inter-actions.

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.
