52_17/2013Cover Picture: Chiral Magnesium(II) Binaphtholates as Cooperative Brønsted/Lewis Acid–Base Catalysts for the Highly Enantioselective Addition of Phosphorus Nucleophiles to α,β-Unsaturated Esters and Ketones (Angew. Chem. Int. Ed. 17/2013)

Supramolecular catalysts relying on cooperation between Mg ions and a chelating complex (represented by carp in the picture) were developed by K. Ishihara and co-workers in their Communication on page 4549 ff. The enantioselective 1,4-hydrophosphinylation of α,β-unsaturated esters with diaryl phosphine oxides and 1,2-hydrophosphonylation of α,β-unsaturated ketones with dialkyl phosphites was achieved using chiral 3:2 complexes of (R)-(H8-)BINOLate/MgII ions.
