dioxane-water and in methanol at 25 o C are reported. These substitutions result in >150-fold differences in their rates of acid-catalyzed solvolysis and cause marked changes in the distribution of solvent adducts and phenols resulting from isomerization. Optically pure BA-O, 7-MBA-O, 12-MBA-O, and 7,12-DMBA-O as well as their optically pure trans dihydrodiols were utilized to determine the point of attack by
苯并 [a] 蒽 5,6-氧化物 (BA-O) 在取代 1 (1-MBA-O)、4 (4-MBA-O)、7 ( 7-MBA-O)、11 (11-MBA-O) 和 12 (12-MBA-O)、7,12-二甲基取代 (7,12-DMBA-O) 和 7-溴取代1:9 二恶烷-水和甲醇在 25 o C 报告。这些取代导致其酸催化溶剂分解的速率差异 > 150 倍,并导致异构化导致的溶剂加合物和酚类的分布发生显着变化。利用光学纯的 BA-O、7-MBA-O、12-MBA-O 和 7,12-DMBA-O 以及它们的光学纯反式二氢二醇来确定水解反应中水的攻击点
