Zm. Li et al., Highly selective reaction of propargyl bromide with carbonyl compounds promoted by metal dysprosium, ACT CHIM S, 58(10), 2000, pp. 1301-1306
Promoted by metal dysprosium, aldehydes and ketones could react smoothly wi
th propargyl bromide to afford the corresponding homopropargylic alcohols i
n good to excellent yields, and no allenic alcohols were found. However, ca
rbonyl compounds only afford the corresponding allenic alcohols when propar
gyl bromide was replaced by 1-phenyl-3-bromopropargyl bromide,and no homopa
rgylic alcohols were formed.
