摘要：

In the oxidative process of the supersilanide anion [SitBu(3)](-), radical species are generated. The continuous wave (cw)-EPR spectrum of the reaction solution of Na[SitBu(3)] with O-2 revealed a signal, which could be characterized as disupersilylperoxo radical anion [tBu(3)SiOOSitBu(3)](-) affected by sodium ions though ion-pair formation. A mechanism is suggested for the oxidative process of supersilanide, which in a further step can be helpful in a better understanding of the oxidation process of isoelectronic phosphanes.
