with solid reagents. We have showcased the practicality of Bertagnini's salts, also called aldehyde-bisulfite adducts, which are crystalline, simplifying preparation and storage. These salts are stable substitutes for liquid aldehydes and ketones that have been effectively employed in reductive amination, synthesizing aza-heterocycles and hydrazones within mechanochemistry. The technique's effectiveness
我们的研究表明,使用固体试剂进行机械
化学活化更有效。我们展示了贝尔塔尼尼盐(也称为醛-
亚硫酸氢盐加合物)的实用性,它们是结晶,简化了制备和储存。这些盐是液体醛和酮的稳定替代品,可有效用于机械
化学中的还原胺化、氮杂杂环和腙的合成。该技术的有效性拓宽了底物范围,简化了纯化,减少了反应时间,并提供了良好的产物收率。此外,
亚硫酸氢盐加合物的热稳定性已通过 TGA(热重分析)分析得到证实。
