attention has been purposefully directed to bimolecular nucleophilic substitution of allyl alkyl ethers, perhaps because of a predetermination that these systems would prove as inert toward displacement as dialkyl ethers. One interesting example known to us is due to Farnum and Monego who showed that dimetalation of
人们有意将注意力集中在
烯丙基烷基醚的双分子亲核取代上,这可能是因为预先确定这些系统将证明与二烷基醚一样对置换呈惰性。我们所知道的一个有趣的例子是 Farnum 和 Monego,他们证明了
