Abstract:
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.
