A new, optically active, atropisomeric diphosphane ligand, (2,3,2′,3′-tetrahydro-5,5′-bi(1,4-benzodioxin)-6,6′-diyl)bis-(diphenylphosphane) (SYNPHOS®), has been synthesized, characterized, and used in ruthenium-catalyzed asymmetric hydrogenations. This new ligand has been compared with other atropisomeric diphosphanes (BINAP and MeO-BIPHEP) with respect to their dihedral angles calculated by molecular
一种新的光学活性阻转异构二膦配体,(2,3,2',3'-四氢-5,5'-bi(1,4-benzodioxin)-6,6'-diyl)bis-(diphenylphosphane) ( SYNPHOS®),已被合成、表征并用于钌催化的不对称氢化。这种新配体已与其他阻转异构二膦(BINAP 和 MeO-BIPHEP)在分子模型计算的二面角和钌介导的氢化反应的对映选择性方面进行了比较。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
