Palladium catalyzed cross-coupling reaction of 5-tributylstannyl-4- fluoropyrazole
The palladium catalyzed cross-coupling reactions of aryl iodides and 5-tributylstannyl-4-fluoropyrazole prepared from fluoro(tributylstannyl) acetylene proceeded smoothly giving the corresponding 5-aryl-4-fluoropyrazole in good yields. The Royal Society of Chemistry 2005.
