Study Notes
- An electrophile is a chemical species that accepts an electron pair from a nucleophile.
- Electrophiles are Lewis acids because they accept electrons.
- Electrophiles interact with nucleophiles through addition and substitution reactions.
- Common electrophiles in organic syntheses include cations, polarized neutral molecules, oxidizing agents, and Lewis acids.
- Hydrogen halides add to alkenes to give alkyl halides in hydrohalogenation.
- The hydration reaction adds a molecule of water to a molecule of ethene and produces ethanol.
- Chiral electrophiles are optically stable and can be used in enantioselective reactions.
- Electrophilicity index is a method to rank electrophiles in order of reactivity.
- Superelectrophiles are cationic electrophilic reagents with greatly enhanced reactivities in the presence of superacids.
- Electrophiles are important in organic chemistry and have many industrial applications.
- Nitromethane can be nitrated with nitronium tetrafluoroborate only in presence of a strong acid like fluorosulfuric acid.
- The nitration occurs via the protonated nitronium dication.
- Gitionic superelectrophiles have charged centers separated by no more than one atom.
- Distonic superelectrophiles have charged centers separated by 2 or more atoms.
- The protonitronium ion is an example of a gitionic superelectrophile.
- F-TEDA-BF4 is an example of a distonic superelectrophile.
- The nitronium tetrafluoroborate used for nitration is a distonic superelectrophile.
- Nitromethane is a colorless, oily liquid with a slightly sweet odor.
- Nitromethane is used as a fuel in racing cars and model engines.
- Fluorosulfuric acid is a strong acid with the chemical formula HSO3F.
