Formylation and acetylation of 7-t-butyl-1,3-dimethylpyrene selectively afforded the 5-mono- and 5,9-di-substitution products depending on the Lewis acid catalyst used, while bromination and nitration afforded the 6-substitution product.
取决于所使用的路易斯酸催化剂,7-叔丁基-1,3-二甲基芘的甲酰化和乙酰化选择性地提供了 5-单和 5,9-二取代产物,而溴化和硝化提供了 6-取代产物。
