1]nonane-7-spirocyclopropane (5) as a result of the oxidative cyclobutane ring contraction. and result only in oxidative addition with the formation of the mixtures of the corresponding 6-hydroxy-3-acetates (7,9) and 3,6-diacetates (6,8). In the case of 2 the only oxidative addition takes place. Possible mechanisms of the backside oxidative addition to the CC bond are discussed.
研究了在不同溶剂中用铬酰氧化剂处理稳定的丙炔3,6-脱氢高金刚烷(1)和1,5-脱氢双环[3.3.1]壬烷(2)的转化。在非极性溶剂中具有CrO 2 Cl 2的烃1在背面氧化添加到应变CC键和3-的过程中形成3,6-dichloro-(3)和3-chloro-6-hydroxy-(4)高金刚烷。氧代双环[3.3.1]壬烷-7-螺环丙烷(5)是由于氧化环丁烷环收缩而产生的。并且仅导致氧化加成并形成相应的6-羟基-3-乙酸盐(7,9)和3,6-二乙酸酯(6,8)。在2的情况下,仅发生氧化加成。讨论了向CC键背面氧化加成的可能机理。
