Chemistry – A European Journal, EarlyView.Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Ruthenium-Catalyzed Ring-Opening and Ring-Closing Enyne Metathesis
, 2016 When a CH2Cl2 solution of an enyne containing the cycloalkene moiety was stirred in the presence of ruthenium−carbene complex (10 mol %) at room temperature under ethylene gas (1 atm), ring-opening and ring-closing metathesis occurred to afford cyclized ...

Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex
Chemistry – A European Journal, EarlyView.Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.
