phosphorus in place of aluminum to form the novel zwitterionic fluorinated phosphorus(V) heterocycleN(PCl2NMe)2PF4 (11). The ethyl-substituted aluminatophosphazene N(PCl2NMe)2AlMeEt (14) reacted cleanly with a 1:1 mixture of [Ph3C][B(C6F5)4] and THF to give the novel donor-stabilized alumazine-phosphazene hybrid cation, [7.THF]+, as the [B(C6F5)4]- salt [N(PCl2NMe)2AlMe.THF][B(C6F5)4] (15).

The cyclic boratophosphazene, N(PCl2NMe)2BCl21, 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)2BF25.
