Kinetic studies on complexation reactions of Li<SUP>I</SUP> with cryptand C211 in <I>N</I>,<I>N</I>-diethyl-<I>N</I>-methyl-<I>N</I>-(2-methoxyethyl)ammonium bis(trifluoromethylsulfonyl)imide (DEMETFSI) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI) have been carried out using <SUP>7</SUP>Li NMR. It was found that the reaction rates in both solutions depend on concentrations of free Li<SUP>I</SUP> and that their kinetic parameters are almost same. From these results, it is proposed that the Li<SUP>I</SUP> complexation reactions in DEMETFSI and EMITFSI solutions proceed though bimolecular mechanism.
