title: Disupersilylperoxo radical anion [tBu3 SiOOSitBu3 ](⋅-) : an intermediate of supersilanide oxidation.
abstract: In the oxidative process of the supersilanide anion [SitBu3 ](-) , radical species are generated. The continuous wave (cw)-EPR spectrum of the reaction solution of Na[SitBu3 ] with O2 revealed a signal, which could be characterized as disupersilylperoxo radical anion [tBu3 SiOOSitBu3 ](⋅-) 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.
