| Resumen en inglés | The unexpected low yield in the Appel's synthesis of PPh2Si(CH3)3 can be attributed to the presence of phenyllithium and its interfering reactions. The method was carried out with hydrolysis of the products formed by the reaction of PPh3 with metallic lithium, phenyllithium and lithiumdiphenylphosphide. PPh2Si(CH3)3 was obtained by subsequent reaction of the resulting diphenylphosphin with elemental lithium and ClSi(CH3)3 |
