    摘要:
    已经研究并解决了长期存在的关于从 KO tBu 到二苯甲酮的电子转移的有争议的报告。KO tBu 的氧化电位不匹配(+0.10 V vs DMF 中的 SCE)和二苯甲酮的第一还原电位(文献中引用的许多值,最小的负值是 -1.31 V vs DMF 中的 SCE),排除直接电子转移。实验和计算结果表明,两种试剂之间形成了一种复合物,钾离子提供了连接,这显着改变了吸收光谱,在可见光区域提供了一条尾巴。在室温下通过特定波长(365 或 400 nm)或什至在冬季日光下进行光活化,导致二苯甲酮羰基钾盐呈蓝色,而当反应混合物保持在黑暗中时没有观察到反应。因此,在基态不发生电子转移。然而,当光激发时,电子转移发生在由二苯甲酮和 KO tBu 形成的复合物中。TDDFT 研究与实验结果相匹配,并将复合物中的电子跃迁定义为 n → π*,起源于丁醇氧。计算和实验也表明该反应对 KO tBu 具有选择性;NaO
