Alkylation by polyprenols of o- and p-cresols in the presence of equimolar amounts of the corresponding aluminum cresolates occurred regioselectively to form o-alkyl products regardless of the ratio of starting reagents. Production of 2,6-dipolyprenyl-4-methylphenol was favored if an excess of polyprenols was used with aluminum p-cresolate. A significant amount of polyprenol polymerization products was obtained under the studied reaction conditions.

邻甲酚和对甲酚的聚异戊二烯醇烷基化：异构聚异戊二烯甲酚的合成

在等摩尔量的相应甲酚铝存在下，邻甲酚和对甲酚的聚异戊二烯醇烷基化反应区域选择性地形成邻烷基产物，而不管起始试剂的比例如何。如果过量的聚异戊二烯醇与对甲酚酸铝一起使用，则有利于 2,6-二聚异戊二烯基-4-甲基苯酚的生产。在研究的反应条件下获得了大量的聚异戊二烯聚合产物。
