Abstract

The first example of a -phosphanylphosphorane, Flu═PCy-PCy (; Flu = 9-fluorenyl), has been easily prepared by P-phosphination of lithiated 9-dicyclohexylphosphinofluorene (FluPCy, ) with chlorodicyclohexylphosphane. constitutes a new type of P(III)-P(V) organophosphorus compound, a σλ-σλ species that is stable under an inert atmosphere in the solid state. The reaction of with [Rh(diene)]BR causes metalation of the benzylic carbon (C9) of fluorene, giving κ-C,P complexes in which fluorene is coordinated in the η form. A complex with the weakly coordinating BArF anion has been isolated and fully characterized, including its crystal structure obtained by X-ray diffraction.
