Direct Mechanocatalysis: Using Milling

Apr 21, 2021To dive into this topic, we want to exemplarily illustrate the first report on direct mechanocatalysis from 2021. Mack and co-workers performed a mechanochemical Sonogashira reaction (Figure 1 A). In this pioneering work, palladium was still added as a catalyst powder but the co-catalyst was Cu in the form of milling balls.
