solvent-free high speed ball milling conditions. Using 2-methylcyclohexanone as the substrate and sodium hydroxide or lithium hexamethyldisilazide as the base, we were able to trap the thermodynamic or kinetic enolate in high selectivity. Although all the reagents were ball milled simultaneously, we observed no products resulting from aldol condensation.
我们研究了在无溶剂条件下选择性形成由动力学或热力学烯醇化物产生的产物的能力 高速球磨条件。使用
2-甲基环己酮 作为基材和
氢氧化钠 或者 六甲基二
硅叠氮化
锂作为基础,我们能够以高选择性捕获热力学或动力学烯醇化物。尽管所有试剂都是同时球磨的,但我们没有观察到醛醇缩合。
