Staudinger reactions of the β‐ferrocenylvinyl azide 1 with several diphosphanes in a 1:1 molar ratio afford the monoiminophosphorane derivatives 2–4, whereas with a 2:1 stoichiometry these reactions afford the bis(iminophosphoranes) 5–7. Similar results are obtained for the reactions of 1 with tris(...
