Abstract

Carbon dioxide was found to promote allylation of aldehydes and ketones. The results showed that in the presence of 1.0 MPa of CO₂, 2 equiv. of Sn, and THF/H₂O, allylation of aromatic aldehydes with allyl bromide was carried out smoothly in good yields, whereas aromatic ketone and aliphatic aldehyde reacted with allyl bromide, respectively, to afford the corresponding products in low yields.

Key words: allyl bromide, tin, allylation reaction, aldehyde and ketone, carbon dioxide
