3 ± 0.8 for the DMSO system. The differences in reactivities between ILs and nonaqueous solvents were proposed to be attributed to those in the chemical forms of the uncomplexed Li(I) species, i.e., the negatively charged species ([Li(X)2]−) in ILs, and the positively charged ones ([Li(solvent)n]+) in nonaqueous solvents.
