The H-atom transfer (HAT) reactivity of a corrolazine cobalt superoxide with weak O-H and N-H substrates has been demonstrated. Kinetic analysis shows relatively fast rates of HAT with diphenylhydrazine (DPH). A kinetic isotope effect (KIE) and Eyring activation parameters are consistent with an HAT mechanism.
已经证明了具有弱 O-H 和 N-H 底物的冠状钴超氧化物的 H-原子转移 (HAT) 反应性。动力学分析表明与二苯肼 (DPH) 的 HAT 具有相对较快的速率。动力学同位素效应 (KIE) 和 Eyring 活化参数与 HAT 机制一致。
