The kinetic behaviour of Diels-Alder and ene reactions was investigated in several inorganic perchlorate-organic solvent solutions. The observed rate accelerations are the result either of specific solute-cation interactions or of the increased internal pressure of the media, depending on substrates, solvents, and metal cations.
在几种无机高氯酸盐-有机溶剂溶液中研究了Diels-Alder和烯反应的动力学行为。观察到的速率加速是特定溶质阳离子相互作用或介质内部压力增加的结果,具体取决于基材,溶剂和金属阳离子。
