    A Ball‐Milling‐Enabled Reformatsky Reaction Cao 2019

    With the optimized ratio of reagents in hand, a reaction time study assessed four individual reaction times of 0.5, 1, 1.5, and 2 h (Table 1, entries 2 and 7–9), which indied that the reaction needs 2 h to afford complete conversion. A control experiment, whereby zinc was omitted from the reaction, returned none of the desired product.

    Mechanical Milling: a Top Down Approach for the Synthesis

    This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. It is highly energetic compared to the attrition and vibratory mills. A given reaction can typically take place an orderofmagnitude faster in the SPEX mill than in the typical attritor or vibratory mill.
