2-Chloromethyl and 3-chloromethyl-1,6-methano[10]annulene systems solvolyze in methanol to give simple substitution products. Solvent effect studies and the special salt effect support the involvement of cationic intermediates stabilized by the 1,6-methano[10]annulene group. Rate data indicate that the degree of cation stabilization greatly exceeds that of naphthyl groups. B3LYP/6-31G computational
2-氯甲基和3-氯甲基-1,6-甲基[10]环戊烯系统在甲醇中溶剂分解,得到简单的取代产物。溶剂效应研究和特殊的盐效应支持了由1,6-甲基[10]环戊烯基稳定的阳离子中间体的参与。速率数据表明,阳离子稳定度大大超过了萘基。B3LYP / 6-31G的计算研究还表明,阳离子中间体被1,6-甲基[10]环戊烯稳定。与这些发现相反,溶剂分解和计算研究表明11-(1,6-甲基[10]环戊烯基)阳离子是环庚三烯基阳离子的失稳类似物。与环环没有有利的相互作用。
