Abstract

The reactions of 2-ethylthio-5-diphenylphosphino-furan (TPF) with [Rh2(CO)4-(μ-Cl)2 (or with [Ir2(COD)2Cl2] under CO) have been shown to lead to [Rh2-(TPF)2(CO)2(m-Cl)2], trans-[Rh(TPF)2(CO)Cl] or the cationic [M(TPF)2(CO)3]+ 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 [Au-(TPF)2Cl] derivative with monodentate P-bound ligands has also been prepared, and shown to react with [Rh2(CO)4(μ-Cl)2] to yield rhodium-gold heterobinuclear adducts as mixtures of head-to-head and head-to-tail isomers.
