摘　　要：The reactions of carbonyls with a low-valent titanium reagent prepared by TiCl4with Mg in THF were carried out under ultrasonic action at room temperature for 10 min to1 h and corresponding olefins were obtained in good yields. The results indicate that the titanium-induced reductive coupling of carbonyls to olefins is directly affected by ultra sonic dueto the electron transfer process.The reactions of carbonyls with a low-valent titanium reagent prepared by TiCl4with Mg in THF were carried out under ultrasonic action at room temperature for 10 min to1 h and corresponding olefins were obtained in good yields.
