, p. 1403 - 1411 (2007/10/03)
The solvolysis rates of 1-(substituted phenyl)-1-phenyl-2,2,2-trifluoroethyl and 1,1-bis(substituted phenyl)-2,2,2-trifluoroethyl tosylates or bromides were conductimetrically measured at 25.0 °C in 80% aqueous ethanol. The substituent effects on these so

Reagents and procedures for the preparation of tert-butyl sulfonate esters 2 and 2,2,2-trifluoro-1,1-diphenylethane sulfonate esters 3 (TDE-sulfonates) are described.In these new sulfonates, S-O-scission is reduced significantly by steric hindrance.
SOLVOLYTIC STUDIES OF THE HIGHLY CROWDED 1-ARYL-1-PHENYL-1-(TRIFLUOROMETHYL)METHYL BR0MIDE AND TOSYLATES
Liu, Kwang-Ting,Kuo, Mann-Yan
, p. 355 - 358 (2007/10/02)
In the titled system the remarkably high tosylate/bromide solvolysis rate ratio of 1.56E6:1 indicates a highly strained ground state, and the reverse order of reactivity for substrate having l-(4-trifluoromethyl)phenyl vs. that having 1-(3-trifluoromethyl
