Proton‐coupled electron transfer (PCET) is currently intensively studied because of its importance in synthetic chemistry and biology. In recent years it was shown that redox‐active guanidines are capable PCET reagents for the selective oxidation of organic molecules. In this work, the scope of their PCET reactivity regarding reactions that involve C−H activation is explored and kinetic studies carried
由于其在合成化学和生物学中的重要性,目前对质子偶联电子转移(PCET)进行了深入研究。近年来,已证明氧化还原活性胍是能够选择性氧化有机分子的PCET试剂。在这项工作中,探讨了涉及涉及CH活化的反应的PCET反应性范围,并进行了动力学研究以揭示反应机理。相对于二茂铁/二茂铁,电位高达1.2 V的有机分子被有效地氧化。反应由电子转移引发,然后由电子转移平衡开始缓慢的质子转移。
