A new, alternative route to polycyclic organophosphorus cages and to complexes with η 5 ‐1,2,4‐triphospholyl or η 4 ‐1,2,4‐triphosphole ligands is afforded by the moderate stability of the P−Sn bond in 1‐triorganylstannyl‐1,2,4‐triphosphole derivatives (see scheme). These compounds are readily accessible from the corresponding triphospholyl sodium salts. All the reactions of the stannyl triphospholes tested so far give good to almost quantitative yields with high chemo‐ and diastereoselectivity.
