theranostics for diseases accompanied by pathological function of proteins involved in choline transport. Unlike choline analogues labeled with 11C or 18F that are currently used in the clinic, the iodinated compounds described herein are applicable in positron emission tomography, single-photon emission computed tomography, and potentially in therapy, depending on the iodine isotope selection. Moreover

A series of 4'-substituted phenyl-4-piperidinylmethanol and benzoyl-4-piperidine derivatives was synthesized as potential novel serotonin 5-HT2A receptor ligands that can be radiolabeled for in vivo brain imaging. Compounds were prepared by alkylation of 4-substituted benzoyl-4-piperidine with an iodo- or fluoro-substituted phenylalkyl halide followed by reduction with sodium borohydride. Potency of
Palladium-catalyzedcarbonylative cross coupling reaction of organofluorosilanes with organic halides was achieved in the presence of fluoride ion and an atmospheric pressure of carbon monoxide. Alkenyl- or arylfluorosilanes effectively underwent this reaction with alkenyl or aryl iodides in moderate to good yields. Thus, highly functionalized ketones are readily available without protection of reactive
