โœฆ Synopsis


The reproducible preparation of [1-11C]propenoic acid (acrylic acid) in 45-50% radiochemical yield was made possible by careful control of the temperature and time of the 11C carbonation of ethenylmagnesium bromide. It allowed the obtention of [1-11C]propenoyl chloride and N-[1-11C] substituted propenamides. These latter were highly reactive as it was shown by the obtention of a Michael adduct with secondary amines even at room temperature.

The optimal conditions for the catalytic production of [11C]HCN from [11C]CO2 were investigated. [11C]CO2 was reduced to [11C]CH4 with H2 on Ni and then converted to [11C]HCN by reaction with NH3 on Pt in a radiochemical yield of more than 95% under the optimized conditions of an NH3 concentration o

## Abstract Roxithromycine, a new macrolide, was labelled with [^11^C]CH~3~I in a good radiochemical yield (40โ€45%)and high specific activities (500โ€550mCi/ฮผmol). This antibiotic may be useful for detecting pulmonar or cerebral infection foci using positron emission tomography.
