Cover Feature: Multispin Systems with a Rigid Ferrocene‐1,1′‐diyl‐Substituted 1,3‐Diazetidine‐2,4‐diimine Coupler: A General Approach (Eur. J. Org. Chem. 7/2022)

The Cover Feature shows a beautiful sunrise metaphorically representing the boundary between chemistry and physics, the interaction of which has paved the way for the synthesis of a biradical with a ferrocene-derived inflexible bridging moiety. This is a versatile route and could be used to prepare weakly coupled biradicals with different spin-bearing groups and with a redox-active ferrocene part.
