Allylation Reactions of Aromatic Aldehydes with Antimony in Aqueous Media Under Ultrasonic Irradiation

The allylation reactions of aromatic aldehydes with allyl bromide were carried out in 89-98% yield with Sb-H 2 O-KF-CH 3 OH under ultrasound irradiation at rt for 2.5 h. The reactions in the same system gave allylic alcohols in 30-69% yield with stirring for 24 h. The main advantages of the present...

More Information
Summary:The allylation reactions of aromatic aldehydes with allyl bromide were carried out in 89-98% yield with Sb-H 2 O-KF-CH 3 OH under ultrasound irradiation at rt for 2.5 h. The reactions in the same system gave allylic alcohols in 30-69% yield with stirring for 24 h. The main advantages of the present procedure are shorter reaction time, better yield, and environmental friendliness.
