Eusamio, JavierSaumell Palacios, NilVidal Ferran, AntonGrabulosa, Arnald2026-02-182026-02-182024-07-180020-1669https://hdl.handle.net/2445/227015The first example of a P-phosphanylphosphorane, Flu�PCy2−PCy2 (L2; Flu = 9-fluorenyl), has been easily prepared by P-phosphination of lithiated 9-dicyclohexylphosphinofluorene (FluPCy2, L0) with chlorodicyclohexylphosphane. L2 constitutes a new type of P(III)−P(V) organophosphorus compound, a σ3 λ3 −σ4 λ5 species that is stable under an inert atmosphere in the solid state. The reaction of L2 with [Rh(diene)2]BR4 causes metalation of the benzylic carbon (C9) of fluorene, giving κ2 -C,P complexes in which fluorene is coordinated in the η1 form. A complex with the weakly coordinating BArF anion has been isolated and fully characterized, including its crystal structure obtained by X-ray diffraction.5 p.application/pdfeng(c) American Chemical Society, 2024info:eu-repo/semantics/article7498352026-02-18info:eu-repo/semantics/openAccess
