- Abstract
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 cross-coupling.
