are readily cleaved by metallic magnesium in absolute tetrahydrofuran forming allylmagnesium naphtholates in excellent yields. The cleavage of 2-methylallyl β-naphthyl ether, on the other hand, proceeds slowly giving good yields only after long reaction times. With 2-methylallyl α-naphthyl ether yields are low even after very long reaction times. Wurtz-type coupling products are never observed.
α-萘酚和β-萘酚的烯丙基醚很容易在绝对四氢呋喃中被金属镁裂解,从而以极好的收率形成烯丙基萘甲酸镁。另一方面,仅在长的反应时间之后,2-甲基烯丙基β-萘基醚的裂解缓慢进行,得到良好的产率。使用2-甲基烯丙基的α-萘醚即使经过很长的反应时间,收率仍然很低。从未观察到Wurtz型耦合产品。
