A Mechanochemical Zinc-Mediated Barbier-Type Allylation

ABSTRACT: A Ball -milling enabled zinc mediated Barbier type allylation reaction is reported. Notably runnning the reaction in this manner renders it effective irrespective of the initial morphology of the zinc metal. The process is operationally simple, does not require inert atmospheres or dry solvents and is reported on a range of

Ball Mill an overview ScienceDirect Topics

The milling time increases with a decrease in the specific energy of the mill. Thus, a process that takes only a few minutes in a planetary mill can take hours in attritors and several days in commercial tumbling ball mills. Commercial batch NETZSCH attritors (Fig. 3.12) used industrially today are available in sizes from 115 to 720 L (Table 3.3).
