6-Bromo-3,3-dichloro-1-methyl-1H-2,1-benzothia-zin-4(3H)-one 2,2-dioxide
Abstract:
The monomeric title compound, C(9)H(6)BrCl(2)NO(3)S, has an envelope-shaped thia-zine ring with the S atom 0.879 (9) Å out of the mean square plane of the envelope. The π-π distances between the centroids of the heterocyclic rings are 4.191 (5) and 4.110 (5) Å. The closest intermolecular inter-actions between the O atoms of the carbonyl and sulfonyl groups with Br and Cl atoms are 2.987 (7) and 2.992 (8) Å, respectively.

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...
