Assembly of Effective Halide Receptors from Components. Comparing Hydrogen, Halogen, and Tetrel Bonds.

Abstract

Receptors for halide anions are constructed based on the imidazolium unit and then replacing the H-bonding C-H group first by halogen-bonding C-I and then by tetrel-bonding C-SnH3 and C-SiF3. Attaching a phenyl ring to any of these species has little effect on its ability to bind a halide, but incorporation of a second imidazolium to the benzene connector… (More)
