The combination of Pd(PCy3)2Cl2 and di-2-pyridyl ketone catalyzes a reductive formylation of aryl iodides with carbon dioxide as the carbonyl source under mild reaction conditions in the presence of phenylsilane as the reductive reagent. This convenient reaction provides a variety of aromatic aldehydes in good yields with wide substrate scope and good functional group tolerance.
