Abstract:
We recently introduced multidentate halogen-bonding receptors based on C-iodinated ortho-Carborane moieties. Following up on our results in solution, which indicated a second binding event for sub-stochiometric concentrations of halide guests, we herein present a systematic co-crystallization study with halides to further evaluate the halogen-bonding capacities of these halogen-bonding catalysts. The obtained solid-state structures include two rare examples of octahedral coordination via halogen bonding of a halide ion by a pair of tridentate receptors.

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...
