General Introduction
The direct carbonylation of an appropriately activated arene appears to be the most straightforward approach for the synthesis of arenecarbaldehydes. Because many transition-metal complexes are able to coordinate to carbon monoxide, aryl transition-metal reagents seem to be promising intermediates for the development of such processes. However, the discovery of efficient catalysts for this transformation has been elusive, and only palladium complexes have emerged so far to be broadly applicable for arene carbonylation.
