|Type 18 Lewis Acid/Base Complexation Chemistry |
|Cationic π-System Salts |
|Bonding: || |
Charge controlled ionic complexes which form solvent separated ions in polar solvents so making the interesting π-cations appear ‘naked’ for spectroscopic study.
Species can only be truly naked under high vacuum vapour phase conditions or in mathematical in silico computer models.
|Charge: || Complexes are neutral. |
|Chemistry: || |
Exotic cationic π-systems, such as allyl & pentatrienyl cations:
cyclopropenyl, cyclobutdienyl, tropylium & cyclooctatetrenely cations:
are reactive electrophilic entities that require very non-nucleophilic anionic counter ions, and tetrafluoroborate, [BF4]–, and hexafluorantimonate, [SbF6]–, type ions are ideal.
|Congeneric Series: || Few of interest. |
