The transition-metal-catalyzed decarboxylation of aromatic carboxylic acids has emerged as an exciting strategy in organic synthesis because it enables the formation of aryl–metal intermediates by loss of CO2. This process can provide unconventional alternatives to perform various types of CÀ C and CÀheteroatom bond-forming reactions relative to typical organometallic reagents.[1] It is known that transition-metal-catalyzed cross-coupling ...
