Arenediazonium tetrafluoroborates (ArN2BF4 where Ar = X-C6H4; X = H, 2-Me, 3-Me, 4-Me, 4-MeO, 4-MeCO, 4-EtOCO, 2-Ph, 2-Cl, 3-Cl, 4-Cl, 4-Br, 4-I, 3-NO2 and 4-NO2) were easily converted to aromatic aldehydes (ArCHO) in good yields through the palladium-catalyzed reaction with CO and Et3SiH or polymethylhydrosiloxane (PHMS) at room temperature.
