Abstract
The effect of nucleophilic anions on the rate constants for reaction of 1-(4-methoxyphenyl)-2,2,2-trifluoroethyl iodide (1-I) and bromide (1-Br) in water at 25 o C and a constant ionic strength of 6.00 maintained with perchlorate ion has been determined. These substrates react by a D N +A N (S N 1) mechanism through the 1-(4-methoxyphenyl)-2,2,2-trifluoroethyl carbocation intermediate (2), which is captured by I - , N 3 - , and SCN - in diffusion-limited reactions
