Synthesis and purification of 2-deoxy-2-[18F]fluoro-d-glucose and 2-deoxy-2-[18F]fluoro-d-mannose: characterization of products by 1H- and 19F-NMR spectroscopy
The capping of “living” poly(methyl methacrylate) (PMMA) and “living” polystyrene (PS), both prepared by the RAFT technique, with various olefins was screened using 19F-NMR spectroscopy. The capping of “living” PMMA with a labeled stilbene was as high as 63% and with certain cinnamate esters was essentially quantitative, but the capping of “living” polystyrene with all the olefins investigated was generally poor.
