With the right metal–ligand combination anything seems possible. Schrock et al. ( Angew. Chem. Int. Ed. Engl. 1993 , 32, 756) stabilized nucleophilic phosphinidene ligands without bulky substituents at the tantalum centers with the help of the ingeniously constructed triamido ligand N 3 N. These complexes [(N 3 N)TaPR] react smoothly with a large number of aldehydes to give oxotantalum complexes and phosphaalkenes. These results should stimulate, among other things, the extension of this approach to the As and Sb homologues.
