Experimental and computational studies have revealed that the efficiency of intramolecular oxidative cross-coupling reactions is governed by the SOMO–HOMO gap of the coupling partners, and that the reaction efficiency can be predicted by the oxidation potential gap (ΔEox). Furthermore, tuning of the ΔEox value by the addition of cleavable electron-donating or -withdrawing groups enabled the electrochemical
实验和计算研究表明,分子内氧化交叉偶联反应的效率受偶联伙伴的 SOMO-HOMO 间隙控制,并且反应效率可以通过氧化电位间隙 ( ΔEox )来预测。此外,通过添加可切割的给电子或吸电子基团来调整ΔE ox值,使得菲啶酮骨架的电化学合成成为可能。
