Abstract
The rate of reaction of a Menschutkin process in a range of ionic liquids with different cations was investigated, with temperature-dependent kinetic data giving access to activation parameters for the process in each solvent. These data, along with molecular dynamics simulations, demonstrate the importance of accessibility of the charged centre on the cation and that the key interactions are of a generalised electrostatic nature.
摘要
研究了曼许特金反应在一系列具有不同阳离子的离子液体中的反应速率，温度依赖的动力学数据为每个溶剂中的过程提供了活化参数。这些数据以及分子动力学模拟表明，阳离子上带电中心的可及性以及关键相互作用具有广义静电性质的重要性。
