Notes:
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(diphenylphosphanylmethyl)ethane (triphos) and tris[2-(diphenylphosphanyl)ethyl]phosphane (tetraphos). Reaction of these P,N-difunctional ferrocene ligands with dichlorobis(benzonitrile)palladium(II) leads to the PdII-metallacycle derivatives 13 and 14. The molecular structures of 5d and 13 have been established by X-ray crystallography.
