Synthesis of Homoallyl Alcohol by Allyl samarium Bromide and Carbonyl Compounds

Abstract

Abstract: 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, ¹HNMR and MSspectra.

Key words: Samarium, Allylsamarium bromide, Homoallyl alcohol, Addition
