The reactions of 2-ethylthio-5-diphenylphosphino-furan (TPF) with (or with under CO) have been shown to lead to trans or the cationic ⁺ species, (M = Rh, Ir), all with monodentate phosphorus-bound ligands.The latter gives rhodium-silver and rhodium-iridium heterobinuclear head-to-head <(CO)3Rh(μ-TPF)2Ag>²⁺ and <(CO)3Ir(μ-TPF)2Rh(CO)3>²⁺ derivatives.A monomeric derivative with monodentate P-bound ligands has also benn prepared, and shown to react with to yield rhodium-gold heterobinuclear adducts as mixtures of head-to-head and head-t-tail isomers.
