Abstract:
The title compound, C(16)H(12)Br(2)F(2)S(2) [systematic name: 1(2),1(5)-dibromo-5(2),5(5)-difluoro-2,7-dithia-1,5(1,4)-dibenzenaocta-phane], has two approximately parallel benzene rings with a dihedral angle of 1.53 (15)° between them and with a centroid-centroid distance of 3.3066 (18) Å. In the crystal structure, mol-ecules are stacked along the a axis through an inter-molecular π-π inter-action with a centroid-centroid distance of 3.7803 (18) Å. Mol-ecules are also connected by a C-H⋯S inter-action, forming a chain along the b axis.

Halogenation of Alkenes
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.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
