The "cation pools" of alkoxyarylcarbenium ions were effectively generated by the oxidative C-C bond dissociation using low temperature electrolysis. The present method is especially effective for the generation and accumulation of dications, which react with carbon nucleophiles. Copyright
Solvolysis of α-t-Butylbenzyl arenesulphonates: A Prototypical SN1 Process.

Solvolyses of α-t-butylbenzyl arenesulphonates are studied with a view to correlating the magnitude of the cross-interaction constants, ρxy, ρxz and ρyz (where X, Y, and Z denote nucleophile, substrate and leaving group, respectively), with the SN1 transition state (TS) structure.As postulated for a limiting SN1 process, ρxy and ρxz vanish whereas the ρyz value is exceptionally large.Moreover, the solvent dependence of ρyz indicates an earlier TS along the reaction coordinate as the ion-pair intermediate is stabilized, in accordance with theBEP principle.The large magnitude of the kinetic response, m, to the solvent ionizing power, YoTs, and the ρy' values are within the ranges of values reported for SN1 reactions.The results of kinetic solvent isotope effect studies and the activation parameters, ΔH* and ΔS*, determined are also in line with those expected from a typical SN1 mechanism.

The reaction of the chlorides (4)-(6), which are both neopentylic and thenylic, were studied.The chloride (4), unlike its analogue (13) in the benzene series undergoes ready solvolysis with alcohols to give the corresponding ethers, e.g. (7)-(9).The chlor
Barriers to Internal Rotation in Neopentylbenzenes Substituted on the Benzyl Group. A 13C NMR Band Shape Study

, p. 730 - 744 (2007/10/02)
Two series of neopentylbenzenes with one or two substituents on the benzyl group have been synthesized.In one series the substituents were H, F, Cl, Br, I, OCH3, OCOCH3, OSi(CH3)3, CH3 and CH2CH3, and in the other OH and R R = H, CH3, CH2CH3, (CH2)3CH3,
