    The palladium-catalyzed cross-coupling reactions of 5-tributylstannyl-4-fluoro-1H-pyrazole with aryl iodides provided high yields of the corresponding 5-aryl-4-fluoro-1H-pyrazoles. Furthermore, these cross-coupling reactions proceeded smoothly under an atmosphere of carbon monoxide (CO) to afford the corresponding 5-acyl-4-fluoro-1H-pyrazoles as CO-insertion products.
