Inside Back Cover: Crystalline Anions Based on Classical N‐Heterocyclic Carbenes (Angew. Chem. Int. Ed. 5/2023)

Abstract

Stable anions …on classical N-heterocyclic carbenes can be prepared by KC 8 reduction of the corresponding NHC radicals as reported by Diego M. Andrada, Rajendra S. Ghadwal, and co-workers in their Research Article (e202215244). Thek ey to the stability of these anions is the delocalization of the electron lone pair over the C2biphenyl substituent. In the solid state,t he anions form ah exameric tubular structure with biphenyl substituents pointing inwards,a saresult of intriguing cation-p interactions.T he spider weaves its web.
