When FeCl3 was added into Cl to form an ionic liquid, the chemical shift of 2-H shifted downfield, which indicated that 2-H was deshielded by FeCl3 and was easy to disengage from imidazole.

通过Cl/FeCl3离子液体的1H NMR分析发现，咪唑环上的氢质子尤其是2-H的化学位移与FeCl3含量密切相关，随着FeCl3与Cl摩尔比的增大，2-H的化学位移向低场移动，说明其去屏蔽作用增强，2-H更容易脱离。
