摘要：

Synthesis, Molecular Structure, and Dynamic Behaviour of 1,3,5‐Triaza‐2,4‐diphospha‐1,4‐pentadienes Chloro(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.
