Advantages of mechanochemical synthesis using ball milling include the avoidance of potentially harmful organic solvents and external heating, shorter reaction times, and simpler operational handling. Additionally, mechanochemical reactions are particularly useful for substrates that are poorly soluble in common organic solvents.
