Résumé

A series of paramagnetic di(aryl)alkynylphosphine oxides 3a-c[PF₆] featuring an open-shell [Fe(κ²-dppe)(η⁵-C₅Me₅)]⁺ endgroup were obtained by oxidation of their neutral Fe(ii) parents 3a-c, themselves obtained in a simple and nearly quantitative fashion from the corresponding Fe(ii) metallophosphines 1a-c. The new organometallic radicals were characterised by NMR and ESR and were shown to be perfectly stable in solution, in contrast to species such as 1a-b[PF₆] which readily dimerise.
