摘要

Aromatization of highly alkyl-substituted dihydroanthracene was performed with the n- BuLi/TMEDA/MeI. Treatment of 1, 2, 3, 4, 5, 6, 7, 8-octapropyl-9, 10-dihydroanthracene with 2.2 equiv of n-BuLi, TMEDA at 50° C in hexane for 3 h, followed by 1.1 equiv of MeI at room temperature for 1 h gave the corresponding anthracene in 98% yield.
