The reactions of carbonyls with a low-valent titanium reagent prepared by TiCl₄ with Mg in THF were carried out under ultrasonic action at room temperature for 10 min to 1 h and corresponding olefins were obtained in good yields. The results indicate that the tita-nium-induced reductive coupling of carbonyls to olefins is directly affected by ultra sonic due to the electron transfer process.
