Cover Picture: P-Stereogenic Secondary Iminophosphorane Ligands and Their Rhodium(I) Complexes: Taking Advantage of NH/PH Tautomerism (Angew. Chem. Int. Ed. 28/2012)
Secondary Iminophosphoranes exist as two tautomers in equilibrium. In their Communication on page 6951 ff., A. Riera, X. Verdaguer, and co-workers show that P-stereogenic iminophosphoranes are convenient, configurationally stable, oxidation-resistant pre-ligands. The cover picture shows a tug of war between the forces that shift the equilibrium. In solution the PH form predominates, but in the presence of a metal the equilibrium is shifted towards the PIII form, and the NH team wins!
