The alkylation of phenol with camphene in the presence of boron trifluoride in glacial acetic acid was accompanied by tandem molecular rearrangement with formation of a mixture of ortho- and para-substituted phenols having 1,7,7-trimethylbicyclo[2.2.1]hept-exo-2-yl and 5,5,6-trimethylbicyclo[2.2.1]hept-exo-2-yl substituents. The same products were obtained by rearrangement of 1,7,7-trimethylbicyclo[2.2.1]hept-exo-2-yloxybenzene under analogous conditions. Similar reactions performed in the presence of aluminum phenoxide as catalyst resulted in predominant formation of the corresponding ortho-substituted phenols.
在冰醋酸中,在三氟化硼存在下,苯酚与莰发生烷基化反应,同时发生串联分子重排反应,形成具有 1,7,7- 三甲基双环[2.2.1]庚-外-2-基和 5,5,6- 三甲基双环[2.2.1]庚-外-2-基取代基的正对和对位取代苯酚混合物。在类似条件下,1,7,7-三甲基双环[2.2.1]庚-外-2-基苯通过重排也得到了相同的产物。在有苯氧化铝作为催化剂的情况下进行的类似反应主要生成了相应的正交取代酚。
