An iminophosphenium (monophoshadiazonium) ion is present in the adduct 3 , which is formed upon reaction of the iminophosphane 1 with selenium in the ratio 1:2. The P‐N distance (ca. 150 pm) in 3 is markedly shorter than in iminophosphanes. This and the valence angle at the N atom (ca. 170°) suggest a high proportion of triple bonding in the PN aryl moiety 3 . The structure of this adduct can also be regarded as a “frozen‐in transition state” of an intramolecular selenium exchange reaction.
