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.
使用正丁基锂/TMEDA/碘甲烷对高度烷基取代二氢蒽进行芳构化。在50°C下,用2.2当量的正丁基锂、TMEDA和1.1当量的碘甲烷在己烷中处理1,2,3,4,5,6,7,8-八丙基-9,10-二氢蒽3小时,室温下处理1小时,得到相应蒽的产率为98%。
