sources and 3‐chloroperbenzoic acid (mCPBA) as benign terminal oxidant they catalyze the vicinal diamination of styrenes. The obtained reactivity and selectivity outperform other iodoarene catalyst candidates. This protocol provides a sustainable alternative to previous related protocols for diamination that are based on stoichiometric iodine(III) reagents.
据报道,带有酰胺官能化侧臂的2,6-二取代碘芳烃是氧化还原活性碘(I / III)催化中的新结构。与作为氮源的双磺酰亚胺和作为良性末端氧化剂的3-氯过苯甲酸(m CPBA)结合使用,可催化苯乙烯的邻位加成反应。所获得的反应性和选择性优于其他碘代芳烃催化剂候选物。该协议为基于化学计量碘(III)试剂的先前相关的金属化协议提供了一种可持续的替代方法。
