Reversible skeletal substitution reactions involving group 13 heterophosphazenes.
The cyclic boratophosphazene, N(PCl2NMe)2BCl2 1, reacts with two equivalents of AlMe3 to give the aluminatophosphazene heterocycle, N(PCl2NMe)2AlClMe 4. The unprecedented reverse skeletal substitution (Al for B) was accomplished by treating 4 with Ag[BF4] to form the fluorinated boratophosphazene N(PCl2NMe)2BF2 5.
