Abstract
The ionization of chlorobis(4-methoxyphenyl)methane (1-Cl) was performed in 1:1 mixtures of TFE/ILs (lLs[emim][Tf2N], [bmim][Tf2N], [bpy][Tf2N]), and TFE/CH3CN. The decay of the immediately formed carbenium ion 1(+) was followed by stopped flow, showing that the lifetime of this intermediate significantly decreases on going from CH3CN to [emim][Tf2N]. Ab initio calculations suggest an increase in the electrophilicity of the carbenium ion in ILs. (c) 2005 Elsevier Ltd. All rights reserved.File in questo prodotto:
