Controlled oligomerization of Lewis acid/base-stabilized phosphanylalanes.
PAls should stick together: The cyclo-trimer 2 is obtained by H(2) elimination of Lewis acid/base-stabilized parent compound of the phosphanylalanes 1. The elimination is controlled by fine tuning the temperature and solvent conditions. A subsequent H(2) elimination produces the ladder compound 3. Compounds 2 and 3 are the first of a new class of Group 13/15 compounds which show no additionally donor-acceptor bonds within the framework.
