    • A process for the preparation of pure optically active tertiary phosphines by resolving the corresponding racemic compounds, whereinthe phosphines are first converted to the corresponding phosphine oxides in a conventional manner,the resulting racemic mixtures of the phosphine oxides are reacted in organic solution, in accordance with the principles of enantiomer separation via stereomeric compounds, with an optically pure isomer of a tartaric acid which is mono-acylated or bis-acylated at the alcoholic hydroxyls,the diastereomeric compound which is less soluble in the solvent is separated off,the tartaric acid derivative is split off from the resulting pure diastereomeric compound by means of a base andthe resulting optically pure or substantially optically pure phosphine oxides are reduced back to the phosphines in a conventional manner.The optically active tertiary phosphines may be used as ligands in complex compounds of metals of group VIII of the periodic table, and when such complexes are used as hydrogenating or hydroformylating catalysts they result in substantially stereospecific hydrogenation or hydroformylation of prochiral compounds.
    • 通过拆分相应的外消旋化合物来制备纯的光学活性的叔膦的方法,其中以常规方式首先将膦转化为相应的氧化膦,所得氧化膦的外消旋混合物按有机溶液在有机溶液中反应 通过立体异构体化合物的对映异构体分离原理,在醇羟基上具有单酰化或双酰化的酒石酸的旋光纯异构体,分离出较不溶于溶剂的非对映体化合物,酒石酸 衍生物通过碱从所得到的纯非对映异构体化合物中分离出来,所得光学纯的或基本上光学纯的氧化膦以常规方式还原成膦。 光学活性叔膦可以用作元素周期表第Ⅷ族金属络合物中的配位体,当这种络合物用作氢化或加氢甲酰化催化剂时,它们会导致前手性化合物的基本立体特异性氢化或加氢甲酰化。
