Abstract
[reaction: see text] The ionic liquid butylmethylimidazolium tetrachloroferrate (bmim-FeCl(4)) was found to be a very effective and completely air stable catalyst for the biphasic Grignard cross-coupling with primary and secondary alkyl halides bearing beta-hydrogens. After simply decanting the product in the ethereal layer, the ionic liquid catalyst was successfully recycled four times.
摘要
[反应：见正文] 发现离子液体四氯铁酸丁基甲基咪唑鎓（bmim-FeCl₄）是一种非常有效的、完全在空气中稳定的催化剂，用于与带有β-氢的伯卤代烃和仲卤代烃进行双相格氏交叉偶联反应。只需将产物倾析到醚层中，离子液体催化剂就成功循环使用了四次。
