Mechanochemical Cross-Coupling Reactions
The working mechanism is described in this section. Ball-milling uses one type of grinder that consists of a grinding jar filled with rigid balls (stainless steel balls, zirconia balls, etc.), such as mix mill, planetary mill and rolling mill [45] (Fig. 2a). Depending on the type of movement, different forces are applied.
