Cationic but electron‐rich : Cyclopropenylylidene‐stabilized phosphenium cations exhibit the electron richness of classical trialkyl and triaryl phosphines even though they carry a positive charge stemming from a cationic substituent directly bonded to the phosphorous atom. These two facts have been exploited to synthesize gold catalysts that can be easily recycled after use.
