Allylation reactions of aromatic aldehydes and ketones with lithium in THF under ultrasonic irradiation

The allylation reactions of aromatic aldehydes and ketones were carried out in 69-90% yield using Li-THF system under ultrasound irradiation at r.t. for 40 min. The reactions of the same system with stirring gave homoallyl alcohols in 49-67% yield at r.t. for 4 h.
