The synthesis of 4-[18F]fluoroguaiacol (4-[18F]fluoro-2-methoxyphenol) has been achieved in no-carrier-added form starting from 2-methoxy-4-nitrobenzaldehyde, using nucleophilic aromatic substitution by [18F]fluoride followed by Baeyer-Villiger oxidation of the benzaldehyde to the phenol. Demethylat
## Abstract ^18^Fβlabeled fluorobenzaldehydes and fluorobenzylbromides are useful synthons for the preparation of positron emission tomography radiopharmaceuticals. Although __orthoβ__ and __paraβ__[^18^F]fluorobenzaldehydes can easily be prepared with high yields, the corresponding __metaβ__deriva
Some experience relevant to the production of "F in three chemical forms (['sF]F,, H'sF, 18F.;) via the '-ONe(d, a)18F process using a Ne gas target is described. Production of ['\*F]F2 and H'\*F was done by introducing some technical modifications in standard methods. For '\*F,s production a post i
Fluorination with 18F-F2 and 18F-AcOF were compared for the synthesis of 18F-fluorophenylalanines. L-phenylalanine in CF,COOH trapped 18F-AcOF more effectively than 18F-F2. The main product was ortho-18F-fluorophenylalanine when 18F-AcOF was used as a reagent. Lower radiochemical yield of 18F-fluoro
## Abstract The availability of noβcarrierβadded (n.c.a.) 4β[^18^F]fluorophenol offers the possibility of introducing the 4β[^18^F]fluorophenoxy moiety into potential radiopharmaceuticals. Besides alkylβaryl ether synthesis using n.c.a. 4β[^18^F]fluorophenol the diaryl ether coupling is an attracti
