The solution‐based reaction in dry THF and under nitrogen atmosphere at 50 °C with either zinc flakes or granular zinc (no additive used) resulted in low yields of 7 and 4 %, respectively (Scheme 4 B), whereas under ball‐milling conditions without any solvent, inert gas, or additive (Table 2), the reaction proceeded smoothly in 2 h and all ...
Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
