Abstract
A basic ionic liquid, [bmIm]OH, efficiently promotes a one-pot, three-component condensation of aldehydes, malononitrile, and thiophenols to produce highly substituted pyridines in high yields at room temperature. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid is recovered and recycled for subsequent reactions.
摘要
一种碱性离子液体[bmIm]OH能够在室温下高效地促进醛、丙二腈和硫酚的一锅三组分缩合反应，以高收率生成高度取代的吡啶。该反应不涉及任何有害有机溶剂和有毒催化剂。离子液体可回收并循环用于后续反应。
