Linear oligomerization of 3,5-dimethyl benzyl alcohol is induced by a montmorillonite clay (Tonsil Optimum Extra), producing 1,3,5,7-tetramethyl-9,10-dihydro-anthracene, which, by loss of protons results in the product 1,3,5,7-tetramethylanthracene. It was also found that the compounds 4-(3´,5´-dimethylbenzyl)-1,3,5,7-tetramethyl-9,10-dihydroanthracece and 4-(3´,5´-dimethylbenzyl)-1,3,5,7-tetra-methylanthracene were formed from 1,3,5,7-tetramethyl-9,10-dihydroanthracene. 1,3,5,7-Tetramethylanthryl radical cation was formed from 1,3,5,7-tetramethyl-9,10-dihydroanthracene; it was characterized by Electronic Paramagnetic Resonance (EPR). On the other hand, a theoretical analysis was performed, allowing the rationalization of the observed products and some of the key reaction steps.
蒙脱石粘土(Tonsil Optimum Extra)诱导 3,5-二甲基苯甲醇的线性低聚,产生 1,3,5,7-四甲基-9,10-二氢蒽,通过失去质子导致产品1,3,5,7-四甲基蒽。还发现化合物 4-(3´,5´-二甲基苄基)-1,3,5,7-四甲基-9,10-二氢蒽和 4-(3´,5´-二甲基苄基)-1,3 ,5,7-四甲基蒽由1,3,5,7-四甲基-9,10-二氢蒽形成。 1,3,5,7-四甲基蒽自由基阳离子由1,3,5,7-四甲基-9,10-二氢蒽形成;它通过电子顺磁共振(EPR)进行了表征。另一方面,进行了理论分析,使观察到的产物和一些关键反应步骤合理化。
