Front Cover: Hydrophosphination of Aromatic Alkenes and α,β‐Unsaturated Compounds Using Cobalt Phenoxyimine Complex and Isolation of Double‐Insertion Products (Eur. J. Org. Chem. 7/2026)

The Front Cover shows beautiful crystals of erythrite, also known as red cobalt, which travelers may encounter in certain caves. They serve as markers indicating the presence of cobalt ore. Similarly, the complex developed in the study presented in the Research Article by K. Matsubara and co-workers (DOI: 10.1002/ejoc.202501079) suggests new possibilities for cobalt catalysts.
