Promoted by metal dysprosium, aldehydes and ketones could react smoothly with propargyl bromide to afford the corresponding homopropargylic alcohols in good to excellent yields, and no allenic alcohols were found. However, carbonyl compounds only afford the corresponding allenic alcohols when propargyl bromide was replaced by 1-phenyl-3-bromopropargyl bromide, and no homopargylic alcohols were formed.

Key words: DYSPROSIUM, ALDEHYDES, KETONE
