The following procedures need to be followed to achieve good results i) crushing manganese chips (Aldrich, 99.98%) in a mortar invariably affords a much more reactive metal with respect to the use of commercial manganese powder of the same purity, and ii) immediately before use, trimethylsilyl chloride is purified by elution through a short column packed with basic alumina.
