    摘要: Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like.

    摘要: Methods and reagents for miniaturized carboxylation with carbon-isotope labeled carbon dioxide using Grignard reagents or other organometallic reagents in a closable reaction loop or reactor are provided. The resultant carbon-isotope labeled compounds are useful as radiopharmaceuticals or precursors for radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits for PET studies are also provided.

    摘要: A storage container for alkyl iodide comprising a stabilizing material for an alkyl iodide being disposed inside the container so as to contact an alkyl iodide liquid and an alkyl iodide gas is provided. By disposing the stabilizing material, it represses the decomposition of the alkyl iodide of both the liquid phase and the gas phase and generation of iodine, thereby ensuring the stability of the alkyl iodide itself.
