The Birch reduction–dialkylation reaction has been studied with different aromatic carboxylic acids and primary and secondary bromides. From these results it can be concluded that it is a reasonably general reaction. However, we found important exceptions with the primary bromides: allyl bromide, β-phenethyl bromide, and 5-bromo-2-methyl-2-pentene. The unusual behavior of allyl bromide is briefly discussed
桦木还原-二烷基化反应已用不同的芳族羧酸以及伯和仲溴化物进行了研究。从这些结果可以得出结论,这是一个合理的普遍反应。但是,我们发现主要的溴化物有重要的例外:烯丙基溴,β-苯乙基溴和5-溴-2-甲基-2-戊烯。简要讨论了烯丙基溴的异常行为。
