Graphical Abstract

NP3 ring system: Starting from a highly reactive amino-diphosphene, a dichloro-cycloazatriphosphane (see Scheme) could be synthesized and fully characterized. This new ring system can be regarded as a congener of [XP(μ-NR)]2 and [XP(μ-PR)]2 systems and therefore contributes to a systematic development of NP chemistry.

Abstract

A dichloro-cycloazatriphosphane that incorporates a cyclic NP3 backbone could be synthesized using knowledge gained from the chemistry of N2P2 and P4 ring systems. It fills the gap between the congeneric compounds [ClP(μ-NR)]2 and [ClP(μ-PR)]2 (R=sterically demanding substituent), and thus contributes to the systematic development of nitrogen–phosphorus chemistry in general. The title compound was studied with respect to its formation via a labile aminodiphosphene, which readily underwent different rearrangement reactions depending on the solvent. All compounds were fully characterized by experimental and computational methods.
