Lewis Acid/Base Interaction Matrix Database
|Proton Transfer or Alkylation|
Charge controlled ionic bonding, but... a proton transfer reaction is likely to occur rather than the formation of a complex.
|Charge:||A reaction always occurs, rather than forming a Lewis acid/base complex so the idea of a charge on a complex is not applicable.|
Onium ions generally do not often form complexes with π-HOMO Lewis bases because H+ or R+ transfer (from the onium ion to the π-HOMO Lewis base) is likely to occur.
The acetate ion can be dual classified as both as a Lobe-HOMO and π-HOMO Lewis base (the acetate ion is isoelectronic with the allyl anion). Thus, ammonium acetate can be considered to be a Type 12 complex:
|Congeneric Series:||A reaction always occurs, rather than forming a Lewis acid/base complex so the idea of congeneric series is not applicable.|
|Type 12 Lewis acid/base complex (generic)
