摘要：

Best of both worlds: Related to carbodiphosphoranes and carbodicarbenes (bent allenes), a cyclic vinylidenephosphorane has been isolated and is stable at room temperature (see scheme). It features a very long phosphorus ylide bond, much longer than in the acyclic version, which leaves the carbon lone pair fully available. Accordingly, this species behaves as a strong electron-donating ligand, giving rise to very robust transition-metal complexes. (Chemical Equation Presented). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
