Modulation of in:out and out:out conformations in [X.X′.X′′] phosphatranes by Lewis acids

Abstract

It has been found that P⋯P lone pair-hole intramolecular interactions in phosphatranes are enhanced by the presence of Lewis acid. Interestingly, in:out structures are favored with respect to the out:out ones. This finding opens a chemical way to modulate structural changes and the equilibrium between both structures.
