Herein, we describe the solvent-free ball milling Tishchenko reaction. Using high speed ball milling and a sodium hydride catalyst, the Tishchenko reaction was performed for aryl aldehydes in high yields in 0.5 hours. The reaction is not affected by the type of ball bearing used and can be successful when conducted in a liquid nitrogen environment.
本文中,我们描述了一种无溶剂球磨Tishchenko反应。使用高速球磨和氢化
钠催化剂,可以在0.5小时内以高产率将芳香醛进行Tishchenko反应。反应不受所使用球轴承类型的影响,并且在液氮环境中进行时也能成功。
