Stable Carbocation Generated via 2,5-Cyclohexadien-1-one Protonation

摘要

Protonation of a substituted cyclohexadien-1-one ( 1 ) leads to the generation of carbocation [ 3 ]~(+), capable of effecting hydride abstraction and oxidation reactions. The molecular structure of [ 3 ]~(+) shows it to be structurally similar to [( p -MeO-C_(6)H_(4))Ph_(2)C]~(+). The ability to easily access [ 3 ]~(+) from stable and available precursors, such as 1 and commercially available acids, may allow a wider application of the growing number of trityl-based reactions in organic syntheses.
