International audience; This manuscript discloses the first use of chiral phosphates based on C2-symmetric paracyclophane scaffolds as chiral counterions in transition metal catalysis, showing that they may compare favorably with other known chiral p

International audience; This manuscript reports on a suitable method for the synthesis of paracyclophane type, ferrocene-bridged chiral phosphoric acids, which bear silyl-substituents on their paracyclophane frameworks. These acids have been obtained

Four synthetic equivalents of (iPr2N)2P-OCH2CH2CN (1) have been prepared from readily available enantiomerically pure β-hydroxynitriles as well as from chiral β-hydroxy esters. To demonstrate their possible use as phosphinating/resolving agents, th
Schulleistungsstudien wie PISA haben gezeigt, dass Schülerinnen und Schüler in Deutschland erheblichen Chancenungleichheiten ausgesetzt sind. Sozialindices können vor diesem Hintergrund zur Verringerung von Chancenunterschieden im Bildungswesen be

Key structural feature of the new phosphoramidites is a paracyclophane scaffold in which two aryl rings are tethered by both a 1,8-biphenylene unit and a O—P—O bridge.
