Herein, sulfinylchlorides and styrenes have been exploited to afford either β-hydroxy-phenylethyl sulfides catalyzed by homogenous ZnCl2, or β-chloro-phenylethyl sulfones mediated by heterogeneous CuO nanoparticles (NPs). The key to achieve such a divergent synthetic strategy is the controlled disproportionation process of sulfoxide-onium ions, induced by different metal complexes. Owing to the mild

The mild and high-yielding synthesis of 18F-labeled aryl trifluoromethyl sulfones, -sulfoxides, and -sulfides using [18F]Ruppert-Prakash reagent is described. The application to the radiolabeling of different bioactive compounds using >1 GBq of 18F-labeling reagent is demonstrated. This work expands the radiochemical space of [18F]CF3-containing structural motifs for the use in positron emission tomography
