Photoehcmical addition of acetaldehyde to electron-deficient olefins in the presence of molecular oxygen provides an efficient and mild method for the synthesis of 1,4-functionallzed compounds. Some considerations about the mechanism and the substituent effects are outlined.

The photochemical addition of acyl radical to electron-deficient olefins is studied. The scope of the reaction, the mechanism, the role that molecular oxygen plays, the influence of steric effects, and the side reaction that take place are discussed. The reaction was carried out using a range of electron-withdrawingsubstituents (ketones, amides, lactones, nitrile and esters) with good yields of the
