Uma rota alternativa para a síntese de PPh2Si(CH3)3 segundo Appel; preparação e purificação dePPh2H (Ph = fenila)

Uma rota alternativa para a síntese de PPh2Si(CH3)3 segundo Appel; preparação e purificação dePPh2H (Ph = fenila)

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 lithiumdiphenylp...
