20070249816 - Methods for carbon istope labeling synthesis by rhodium-promoted carbonylation via isocyanate using azides and carbon-isotope monoxide: Methods and reagents for rhodium-promoted carbonylation via isocyanate using carbon-isotope labeled carbon monoxide are provided. The resultant carbon isotope labeled compounds are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits for PET studies are also provided.... Agent: Ge Healthcare, Inc.

20070249817 - Method for producing gaseous diazoalkanes: The invention relates to a method for producing diazoalkanes, which is characterized by dissolving a diazoalkane precursor in a first solvent, dissolving a base in a second solvent, allowing the substances to react in a reactor while forming the diazoalkane and removing the diazoxaline under reduced pressure. The inventive method... Agent: Fulbright & Jaworski, LLP
