Protons (or rather oxonium ions, H3O+) are stopped on the way and rejected because of their positive charges.
Especial interest was aroused theoretically by his work on organic peroxides and oxonium compounds and on the connexion between constitution and colour.
"This lack of reactivity would be unheard of for any other oxonium ion," says
The few oxonium ions that have been isolated and purified are paired with inert counterions and considered among the most powerful alkylating agents in the laboratory.
Mark Mascal and colleagues at UC Davis synthesized the two water-stable alkyl oxonium ions from 1,4,7-cyclononatriene.
Oxatriquinacene, the first stable allylic oxonium ion, is more reactive than oxatriquinane yet significantly more stable than simple alkyl oxonium salts.
Alkyl oxonium ions are widely known as reactive intermediates in organic reactions.
