enantiomer being formed. The products were isolated in high yield and were characterized by single-crystal X-ray diffraction analysis. Their structures in solution were analyzed by 2D 1H–1H ROESY NMR spectroscopy. Subsequent decomplexation and repreparation of the products proved the optical purity of the alcohol-functionalized, chiral diphosphanes formed.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
