摘　　要：高烯丙基醇是有机合成中的一类非常重要的中间体, 以烯丙基金属试剂与羰基化合物加成反应为其主要合成方法[1,2], 常用的金属烯丙基化合物有烯丙基锂(镁、锌、硼、铟、硅、锡、钛)等.Samarium reacts with allyl bromide to form allylsamarium bromide at room temperature in THF. And allylsamarium bromide reacts with carbonyl compounds to give homoallyl alcohols. The yields of products for aromatic aldehydes are higher than those of the products for aliphatic aldehydes. The effect of the group on aromatic ring is not obvious. Two molar allylsamarium bromide reacts with a molar ester to produce the corresponding homoallyl alcohol. The structures of products were characterized by IR, 1H NMR and MS spectra.
