摘要
The oxidation of alpha-tributylstannyl alkanoates With tetrabutylammonium hexanitratocerate(IV) generates alpha-radicals of the alkanoates by eliminating the stannylium ion. The thus-formed radicals react with various electron-rich olefinic compounds, such as silyl enol ethers, giving addition products in good yield. This method formally achieves selective cross coupling between alkanoates and ketones.
