The useful electrophilic fluorinating agent, acetyl hypofluorite, was obtained by passing F2 diluted in N2 through columns containing complexes of alkali metal acetates with acetic acid.Acetyl hypofluorite obtained from KOAc(HOAc)1.5 and o.14percent F2 in N2 was reacted with tri-O-acetyl-D-glucal in CCl3F to obtain tetra-O-acetyl-2-deoxy-2-fluoro-D-glucose in 68percent yield based on F2.These conditions are appropriate to the radiosynthesis of 18F-labeled 2-deoxy-2-fluoro-D-glucose for positron emission tomography.Important variables were the metal cation used, the ratio of HOAc to MOAc and the water content of the complex.
