— In general, the milling ball or vessel is made from a catalytically active component. This novel type of catalysis offers the advantage of directly using solid educts that do not require any solubility. Catalyst recycling and separation is most facile, as the macroscopic milling ball simply has to be taken out of the vessel after the reaction.
