and ultrafast addition of a range of aryllithium reagents to nitriles has been accomplished by using glycerol as a solvent, at ambient temperature in the presence of air, establishing a novel sustainable access to aromatic ketones. Addition reactions occur heterogeneously (“on glycerol conditions”), where the lack of solubility of the nitriles in glycerol and the ability of the latter to form strong intermolecular
逐渐发展为与空气和水分相容的极性有机金属化学,通过在环境温度下在空气中使用甘油作为溶剂,将各种芳基锂试剂化学和超快地添加到腈中,已经建立了一种可持续的新型接触途径。芳香酮。加成反应是异质发生的(“在甘油条件下”),其中腈在甘油中缺乏溶解性以及后者形成强分子间氢键的能力似乎是促进亲核加成而不是竞争性水解的关键。值得注意的是,与在水上相比,PhLi在“甘油”条件下表现出更大的耐水解性能。在有机锂化学中引入甘油作为一种新的溶剂,为开发更具可持续性,
