Ball Milling in Organic Synthesis: Solutions and Challanges

• The scale of the chemical synthesis is related to the type of reaction, the available ball mill(s) and the size of the milling beakers. It is rather recommended to start the reaction at a small scale (≤ 10 mmol) and in case of success perform an up-scaling.
