Allylation of Aldehydes and Ketones with Allyl Bromide and Tin Promoted by Me3SiCI and Alcohol

Abstract
Allylation of aldehydes and ketones to give homoallylic alcohols can be carried out successfully with allyl bromide and metallic tin under anhydrous condition. The 64–89% yields of homoallyl alcohols are obtained by addition of chlorotrimethylsilane as a promoter in anhydrous methanol.
