We report the stereochemistry of reactions of various nucleophiles with optically active silyl esters of phosphorus of general formula: tBuPhP(X)OSiMePhNp (X = −(1), Oxygen (2), Sulfur (3), Selenium (4). The list of nucleophiles includes O,S,N,C nucleophiles as well as halides. The nucleophilic attack is essentially directed towards silicon. The phosphinous and phosphonic acid esters react with predominant
我们报告了各种亲核试剂与磷的光学活性甲硅烷基酯的反应的立体化学,通式为:tBuPhP(X)OSiMePhNp(X =-(1),氧(2),硫(3),硒(4)。的亲核试剂包括O,S,N,C亲核试剂以及卤化物。亲核攻击主要针对硅,次膦酸酯和膦酸酯反应时主要保留了硅原子的构型,而硫代和硒代次膦酸酯类似物产生了反转立体化学交换是根据亲核试剂的亲电子部分与氧基磷酰基或三配位磷的可能相互作用来解释的。
