Novel Method for the Preparation of Triethylsilyl Peroxides from Olefins by the Reaction with Molecular Oxygen and Triethylsilane Catalyzed by Bis(1,3-diketonato)cobalt(II)

In the presence of a catalytic amount of bis(1,3-diketonato)cobalt(II), various olefins react with molecular oxygen and triethylsilane at room temperature to give the corresponding triethylsilyl peroxides in high yields under neutral conditions. The reaction provides a new method for the preparation of various peroxides directly from olefins.
