Atom‐Economical Synthesis of Unsymmetrical Ketones through Photocatalyzed CH Activation of Alkanes and Coupling with CO and Electrophilic Alkenes

A three-component coupling between alkanes, CO, and electron-deficient alkenes in the presence of a catalytic amount of (nBu4N)4W10O32 (TBADT) has resulted in the efficient formation of unsymmetrical ketones. This process is based on the carbonylation of alkyl radicals photocatalytically generated by CH activation of alkanes and the subsequent addition to alkenes (see scheme; EWG=electron-withdrawing group).
