The reference synthesis of Li 3 PS 4 was performed within the high energy ball mill considering a rotational speed of 800 rpm, 10 mm media size and media filling ratio. Due to the active cooling of the grinding jars, the synthesis was performed as a continuous process without the oftenreported process discontinuities caused by cooling breaks.

An environmentally friendly new CH alkylation method of Nheteroarenes facilitated by mechanochemistry is described. Under solventfree ballmilling, mechanoradicals (SO 4 •) were generated from persulfate via in situ homolysis in the solid state, at as low as −50 °C. These highly oxidizing radicals readily transform alkyl trifluoroborate salts to their corresponding carbonbased ...
