We disclose an unprecedented single-step metal-free green oxidation of 2,7-di-tert-butylpyrene selectively into either the corresponding 4,5-dione or 4,5,9,10-tetraone, two key building blocks used for organic optoelectronic applications using hypervalent iodine oxyacids. This new method results in dramatic improvements in terms of yield, selectivity (dione vs. tetraone), ease of workup, cost and toxicity.

立体驱动无金属氧化2,7-二叔丁基py

我们公开了2,7-二叔丁基-空前的单步无金属绿色氧化，选择性地氧化成相应的4,5-二酮或4,5,9,10-四酮，这是有机用的两个关键组成部分使用高价碘含氧酸的光电应用。这种新方法在产率，选择性（二酮对四酮），后处理简便性，成本和毒性方面均取得了显着改善。
