Cover Feature: Mechanochemical C−H Arylation and Alkylation of Indoles Using 3 d Transition Metal and Zero‐Valent Magnesium (Chem. Eur. J. 26/2024)

The ancient Eastern legend of master swordsmiths Gan Jiang and Mo Ye recounts their creation of legendary blades through a harmonious blend of raw materials, skilled craftsmanship, and the application of intense physical energy. The depicted process mirrors this fusion of elements, as the mechanical energy applied to magnesium, akin to the smiths′ hammer strikes, triggers a transformative catalytic reaction that yields chemically enriched 2‐arylindoles.
