Electrochemical fluorination of various (arylthio)methyl carboxylates was carried out in aprotic organic solvents containing poly(HF) salts to provide the corresponding O-fluoromethylcarboxylates in good to moderate yield. Electrochemical fluorination of a cyclic analogue, a γ-phenylthio-γ-butyrolactone derivative was also achieved under ultrasonication to give the corresponding 4-fluorinated product

Disclosed are a photoacid generator, a copolymer, a chemically amplified resist composition, and a method of forming a pattern using the chemically amplified resist composition. The photoacid is connected with a main chain of the copolymer, whereby the photoacid is equally dispersed within a resist layer, and characteristics of line edge roughness of a resist pattern is improved.

Thiol-containing peptides can be radiolabeled with fluorine-18 (F-18) by reacting a peptide comprising a free thiol group with an F-18-bound labelling reagent which also has a group that is reactive with thiols. The resulting F-18-labeled peptides may be targeted to a tissue of interest using bispecific antibodies or bispecific antibody fragments having one arm specific for the F-18-labeled peptide or a low molecular weight hapten conjugated to the F-18-labeled peptide, and another arm specific to the targeted tissue. The targeted tissue is subsequently visualized by clinical positron emission tomography.
