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 ...
