A number of approaches to N-alkyl-N′-phosphanylbenzimidazolium salts were developed. These salts were used for the preparation of stable N-alkyl-N′-phosphanylbenzimidazol-2-ylidenes. Chemical properties of both the salts and the carbenes with O-, N-, and C-nucleophiles were studied. Both salts and the carbenes arepotential ligands for polynuclear complexes.
