Oxidation of α-tributylstannyl ester and amide with CeIV compounds generates α-radicals of acetic acidderivatives with the elimination of the stannyl group. The radicals thus generated react with various electron-rich olefins to give the corresponding addition products in good yield.

of the alkanoates by eliminating the stannylium ion. The thus-formed radicals react with various electron-rich olefinic compounds, such as silylenolethers, giving addition products in good yield. This method formally achieves selective cross couplingbetween alkanoates and ketones.
