Solid‐state synthesis was employed for the preparation of a number of alkaline‐earth‐metal species. In their Full Paper on page 1921 ff., K. Ruhlandt‐Senge et al. describe the solid‐state metalation (apparatus depicted on the background) of 2,6‐diphenylphenol for the facile synthesis of unique heterobimetallic alkaline‐earth‐metal species such as [Na{Ba(Odpp) 3 }]. The compounds display extensive π interactions, providing a significant increase in thermal stability to allow the preparation of compounds deemed previously too unstable for isolation.
