Carbocation Lifetimes that are Independent of Carbocation Stability: the Reaction of α-Substituted 4-Methoxybenzyl Carbocations
Amyes, Tina L.,Richard, John P.

The α-methoxy-4-methoxybenzyl carbocation reacts with the solvent trifluoroethanol-water (50:50 v/v) with a rate constant Ks = 3*107 s-1; ks increases by less than twofold when the carbocation is destabilised by replacement of the strongly electron donating α-OMe substituent by the strongly electron withdrawing α-CF3 substituent.
