ordinary Koch-Haaf carboxylation conditions the tertiary alcohol, 2-(1-adamantyl)-2-propanol (4) yields only the rearranged carboxylic acid, 3-isopropyl-1-adamantane carboxylic acid (5). Mechanistic evidence is presented which indicates that the rearrangement proceeds via intermolecular hydride shifts. A variety of synthetic approaches to the unrearranged 2-(1-adamantyl)-2-methylpropionic acid (1) are described
当经受普通的Koch-Haaf羧化条件时,叔醇2-(1-金刚烷基)-2-丙醇(4)仅产生重排的羧酸3-异丙基-1-金刚烷羧酸(5)。提供了机械证据,其表明重排通过分子间氢化物转移进行。多种合成的接近的未重排的2-(1-金刚烷基)-2-甲基丙酸(1)中有所描述,并且成功地制备1通过的科赫-HAAF反应4高稀释条件下被报告。后面的实验证实了分子间的作用在2-(1-金刚烷基)-2-丙基阳离子(26)的重排中,氢化物转变成3-异丙基-1-金刚烷基阳离子(30)。
