The Stille reaction with 4-[(18)F]fluoroiodobenzene as a novel approach for the synthesis of radiotracers for monitoring COX-2 expression by means of PET has been developed. Optimized reaction conditions were elaborated by screening of various catalyst systems and solvents. By using optimized reaction conditions (18)F-labelled COX-2 inhibitors [(18)F]-5 and [(18)F]-13 could be obtained in radiochemical
