应用烯丙基溴和锡粉在少量水存在下和四氢呋喃中可使醛选择性烯丙基化,这一反应可用于那些同时含有对格氏试剂有反应活性的羟基、酚羟基、芳香族硝基和酮羰基等官能团的醛类以引入烯丙基生成相应的高烯丙基醇.

By using allyl bromide and tin powder in THF in the presence of a small amount of water, a selective allylation of aldehyde containing functional groups reactive toward Grignard reagents such as hydroxyl, phenolic hydroxyl, aromatic nitro and keto groups within the mol. can be achieved. The yield for aliphatic and aromatic aldehydes are in the range of 80-90% and 50-80% resp.
