A Redox‐Active Bis(ferrocenyl)germylene and Its Reactivity

Abstract

Bis(ferrocenyl)germylene Fc*₂Ge: [2; Fc*=2,5‐bis(3,5‐di‐tert‐butylphenyl)‐1‐ferrocenyl] was isolated in the form of red crystals from the reaction of the sterically demanding ferrocenyl lithium dimer (Fc*Li)₂ and GeI₂. Bis(ferrocenyl)germylene 2 exhibits extraordinary thermal stability in hydrocarbon solution and the solid state, as well as stable redox behavior. Moreover, it undergoes a ligand‐redistribution reaction with GeCl₂⋅(dioxane) to afford the corresponding chlorogermylene, which was isolated upon coordination with PBu₃.
