Synthesis, Molecular Structure, and Dynamic Behaviour of 1,3,5-Triaza-2,4-diphospha-1,4-pentadienesChloro(arylimino)phosphane (1) reacts with the 1,3-diaza-2-phosphaallylic system 3 to form 1,3,5-triaza-2,4-diphospha-1,4-pentadienes Ar-N=P-N(R)-P=N-Ar (Ar = 2,4,6-tBu3-C6H2; R = tBu, 2,4,6-iPrc3C6H2) (4a-c). the molecular structure of 4a (“Exo-endo-S conformation”) as well as the dynamic behaviour of the compounds in solution are discussed. the observed temperature dependance of the NMR spectra of 4c was interpreted as a sigmatropic 1,3-rearrangement followed by a P-N rotation.
