This paper describes the improved synthesis of n.c.a. 4- 18F]fluorophenol for the preparation of 18F-labeled alkylarylethers. Nucleophilic fluorination of substituted benzophenone derivatives yielded n.c.a. 4- 18F]fluoro-4'-substituted benzophenones with 80- 90% RCY, which were converted to benzoic acid phenylesters by treatment with peracetic acid. Strong electron-withdrawing substituents like nitro, cyano and trifluoromethyl favor a fluorophenyl-to-oxygen migration resulting in the formation… CONTINUE READING
