Inexpensive ceric ammonium nitrate (CAN) is an efficient oxidant for the Pd-catalyzed substrate-directed o-benzoxylation and decarboxylative o-aroylation processes. In the presence of CAN, the reaction of directing arenes with carboxylic acids resulted in o-benzoxylated products, whereas a decarboxylative o-aroylation occurred by using α-keto acids, which led to the formation of o-aroylation products
廉价的硝酸铈铵 (CAN) 是 Pd 催化的底物导向邻苯甲氧基化和脱羧邻芳酰化过程的有效氧化剂。在 CAN 存在下,定向芳烃与羧酸反应生成邻苯甲酰化产物,而使用 α-酮酸发生脱羧邻芳酰化,从而形成邻芳酰化产物。
