demonstrated the influence of liquid additives on the rate and selectivity of mechanochemical fluorination of aromatic and 1,3-dicarbonyl compounds with F-TEDA-BF4. Substoichiometric catalytic quantities of ionic liquids speed up the reaction. We proposed an improved protocol for ionic liquids-assisted fluorination that allows easy and efficient isolation of fluorinated products by vacuum sublimation. A
我们证明了液体添加剂对 F-TEDA-BF 4芳香族化合物和 1,3-二羰基化合物机械化学氟化的速率和选择性的影响。亚化学计量催化量的离子液体加速反应。我们提出了一种改进的离子液体辅助氟化方案,可以通过真空升华轻松有效地分离氟化产品。仔细选择添加剂可实现氟化产品的高产率和整个工艺的低 E 系数。在这里,我们报告了各种离子液体与代表性分子溶剂比较的基准研究。离子液体添加剂的较低粘度通常与较高的产率和较高的二氟化度相关。含氟阴离子(三氟甲磺酸根和三氟甲酰亚胺)的离子液体被证明是离子液体辅助研磨最有效的催化剂。
