"A diazadiphosphapentalene derivative 5 featuring a\nbent geometry with two phosphorus atoms at the bridgehead has been\nsynthesized. Under mild conditions, compound 5 readily\nactivated ammonia to afford 1-aza-2,3-diphospholene derivative 6 bearing an enamine group. The reaction is therefore viewed\nas a formal σ-bond metathesis between an N–H bond of\nammonia and an endocyclic P–N bond of 5. Details\nof the reaction mechanism for ammonia activation as well as subsequent\nisomerization were explored by density functional theory calculations."
