Syntheses of RC6F4SR′ compounds (where R = F, C6F5, H, R′ = alkyl, trifluorovinyl) have been accomplished through reaction between ArfSM (where M = Cu, MgX) and an alkyl or trifluorovinyl halide in dimethylacetamide solvent. Minor by-products from competing reactions have been partially characterized by GC-MS analysis.

Tris(pentafluorophenyl) phosphine and bis (pentafluorophenyl) sulfide react with ethylmagnesium bromide to give products indicating cleavage of the pentafluorophenyl group from phosphorus and sulfur. Ethylated phosphorus and sulfur compounds as well as pentafluorophenylmagnesium bromide are the principal reaction products. Minor products from subsequent reaction between the Grignard reagents and cleavage
A new and improved method for extending the half life of pharmaceutical compounds for use in diagnostic imaging or therapy uses a novel linker to attach a diagnostic or therapeutic moiety to a targeting peptide or another diagnostic or therapeutic moiety. The resulting compound may have the general formula M-N—O—P-Q, wherein M is the diagnostic or therapeutic moiety, N—O—P is the linker of the present invention, and Q is the targeting peptide. In another embodiment the compounds may have the formula M-N—O—P-M, wherein M is independently a diagnostic or therapeutic moiety and N—O—P is the linker of the invention. Methods for imaging or treating a patient using the compounds of the invention are also provided. Methods and kits for preparing a diagnostic imaging agent from the compound are further provided. Methods for radiotherapy of a patient using the compounds are further provided, as are methods for preparing a radiotherapeutic agent from the compounds.
