AB - The iminophosphenium ion [P=NAr]+ (Ar = 2,4,6-tBu3C6H2) (1) reacts with aminoiminophosphanes R2N-P = NtBu (R = iPr, Me3Si) (2) and alkyl azides RN3 (R = tBu, Et3C) (6) to yield the corresponding [n + 2] cycloadducts [R2NP(NAr)P(NtBu)+ (3) and [PN(Ar)NNN(R)]+ (7), respectively. Single-crystal X-ray diffraction studies show that 3a can be considered as an intramolecular donor-acceptor complex while 7 can be regarded as a cyclic diaminophosphenium cation coupled to a diimine fragment, which is in accordance with results of ab initio calculations.
