Various (hetero)arenecarboxylic acids were converted to the corresponding Daugulis amides and nitrated selectively in the ortho‐position in the presence of [CuNO3(PPh3)2] and AgNO2 at 50 °C. A microwave‐assisted saponification allows regenerating the carboxylate group within minutes, which may then be removed tracelessly by protodecarboxylation, or substituted by aryl‐ or alkoxy‐groups via decarboxylative
在[CuNO 3(PPh 3)2 ]和AgNO 2存在下,在50°C下,将各种(杂)芳烃羧酸转化为相应的Daugulis酰胺,并在邻位选择性地进行硝化。微波辅助的皂化作用可在数分钟内再生出羧酸根,然后可以通过原脱羧作用无痕地除去,或通过脱羧交叉偶联被芳基或烷氧基取代。
