SRN1-type coupling adducts are readily prepared by the reaction between α-sulfonylesters or α-cyanosulfones and gem-dinitro compounds in ionic liquids. The reactions progress smoothly and recovered ionic liquids can be used for several iterations, as long as they are washed with water to remove alkali metallic salts. The reaction rate is slower than the corresponding SRN1 reaction in DMSO, but no acceleration
SRN1 型偶联加合物很容易通过 α-磺酰酯或 α-氰基砜与双硝基化合物在离子液体中的反应制备。反应进展顺利,回收的离子液体只要用水洗涤除去碱金属盐,就可以反复使用。反应速率比 DMSO 中相应的 SRN1 反应慢,但在 m-DNB 存在下没有观察到辐照加速或抑制。
